地基处理效果检测方法研究

黄龙阳

摘要：随着我国各种建设项目的实施，由于各种场地的地质条件特性，往往需要对其进行地基加固处理，而目前的加固处理方法种类繁多，效果差别很大。因此寻找有效的地基处理效果检测方法就显得尤为重要。本文就目前工程中应用较多的地基处理检测技术进行探讨和归纳。

关键词：地基处理；效果；检测方法 前言

随着我国经济技术的迅速发展，各种建设项目开始实施，但通常由于场地地质条件的特殊性，需要对建设场地进行地基加固处理。目前在实际工程建设过程中应用的地基处理方法很多，堆载预压、强夯法、加筋法、换填法、振冲桩、旋喷桩、地基土改良等，但往往由于地基处理方法本身的局限性和施工过程中的人为因素，造成地基处理效果参差不齐。而一个合格的工程场地地基，是建设工程质量安全的重要保障，因此，检测地基加固处理效果的检测技术发挥着越来越重要的作用。目前工程中应用于地基处理效果检测的方法主要有荷载试验、动力触探试验、静力触探试验、十字板剪切试验、波速试验、取芯试验等，但各种试验方法本身适用条件有限，试验精度相差很大。本文结合一些工程实例，对这些检测方法的应用和效果进行探讨。地基处理效果检测试验研究

目前很多学者对地基加固处理效果检测做了各种各样的研究，并对各种方法的优缺点进行了探讨，本文以下仅将工程中应用比较多的进行阐述和归纳。2.1 地基静载荷试验

基静载荷试验是一种精度较高，分析结果与实际吻合度较好的试验方法，用其进行地基承载力测定和地基沉降计算相对准确，但其成本较高，技术要求严格，且试验周期相对较长，一般大型项目的场地勘察均要求进行此项试验。2.1.1 静载荷试验简述 静载荷试验模拟建筑物地基土的受荷条件，在刚性承压板上加荷，荷载通过承压板均匀传递给地基，以测定天然埋藏条件下地基土的变形特性，从而评定地基土的承载力，计算地基土的变形模量和估计基础的沉降量，可以比较直观的反映地基土的变形特性。地基承载力确定方法是：最后当压力－沉降曲线上有比例界限时，取该比例界限所对应的荷载值；当极限荷载小于对应比例界限的荷载值的2倍时，取极限荷载值的一半；当不能按上述两款要求确定时，可取 s/b=0.01所对应的荷载，但其值不应大于最大加载量的一半[1]。2.1.2 静载荷试验评价实例总结

王文奎[2]等采用工字钢和堆料组成压重平台反力系统，用压重平台反力法对长江沿岸某码头后方陆域地基处理工程进行质量检测。预压地基荷载板为边长1m的方形板，由于该工程场地地基处理设计承载力特征值为120kpa，故该次试验最大加载为设计值的2倍，为240kpa，按24kpa每级分级加载，并在加载过程中进行沉降观测，地基承载力特征值的确定。该次试验共计检测20处，p-s曲线上可以看出，当最大加载至240kpa时，所有测点均未达到极限状态，最大沉降量为8.400mm，最小沉降量为6.200mm，根据承载力特征值的取值原则，取最大加载量的一半，即240kpa/2=120kpa为该点处理后地基的承载力特征值，所有测点的承载力均满足设计要求。该工程采用静载荷试验对地基处理进行了评价，说明了该场地经过地基处理，达到了该场地设计的地基承载力120kpa。2.2 十字板剪切试验

十字板剪切试验由于其自身的适用条件限制，一般在沿海地区的软土场地应用较为普遍，而在一些碎石土场地则无法用其进行场地地基处理效果的评判。2.2.1 十字板剪切试验简述

试验时，逆时针方向摇动扭力箱装置小摇手，以每10s转动1°的速度匀速转动，当试验达到峰值或者稳定值后，再测试1min，如试验数据正常，记录峰值数据，根据该数值计算原状土抗剪强度；完成抗剪强度测定后，顺扭转方向连续转动探杆6圈，按照以上步骤进行操作，测定重塑土的不排水抗剪强度。2.2.2 十字板剪切试验评价实例总结

王文奎[2]等采用十字板剪切试验对长江沿岸某码头后方陆域地基处理工程进行质量检测。该次试验共8孔，每孔18个测点，对各孔的检测数据进行统计，通过与原地质勘察资料相比较可知，地基土的抗剪强度有了大幅度提高，地基处理达到了预期效果。2.3 轻型触探试验

轻型触探指N10轻型动力触探仪，其质量较轻，设备简单，应用广泛，操作简便，成本较低，在一些软土地区应用十分广泛。2.3.1 轻型触探试验简述

其利用一定的锤击能量，将带有探头的探杆打入土中，按贯入的难易程度来评价土的性质，主要用于素填土及碎石土地层，并可连续贯入，能在其试验深度范围内不断测得土层的力学特性及变化规律[1]。2.3.2 轻型触探试验评价实例总结

王文奎[2]等采用轻型动力触探试验对长江沿岸某码头后方陆域地基处理工程进行质量检测。现场对56根水泥搅拌桩桩顶下2m范围内的桩头进行了检测，试验结果表明桩顶下2m范围内每30cm锤击数为64-78击，设计值：N10>35击/30cm，检测范围内桩身水泥土均匀，质量满足设计要求。2.4 取芯试验

取芯试验即钻取地基处理后的地基土，然后进行室内试验，用以评价其地基处理后的效果，在一些大型工程中应用也较为普遍。2.4.1 取芯试验简述

对采用旋喷桩、振冲桩、搅拌桩进行地基土处理的场地，在对地基桩取芯试验中，其目的主要是检测桩身混凝土质量情况，检查桩身混凝土胶结状况、有无气孔、松散或断桩等；检查桩底持力层的岩土性状和厚度是否符合设计或规范要求，并核对施工记录桩长是否真实[3]。2.4.2 取芯试验评价实例总结

王文奎等采用取芯试验对长江沿岸某码头后方陆域地基处理工程进行质量检测，共完成16根水泥搅拌桩的检测工作，取芯试验无侧限抗压强度48组，桩身芯样成型长度平均8.5m，成型段芯样成短-中柱状，断口吻合较好，桩身8.30m以下部分桩芯样不成型，未形成强度。芯样强度：共完成强度试验48组，无侧限抗压强度平均值为3.1mpa。

钱归[3]对广明高速公路广州段软基处理后的路基进行取芯检测，其结果岩芯[2]采取率均接近100%，采取率65.4%-74.4%。芯样连续、完整、胶结好、呈长柱状，混凝土桩抗压强度代表值为22.1Mpa，说明该软土地基进行处理后达到了地基处理设计要求。2.5 波速试验

波速试验也是地基处理效果检测的常用手段之一，其设备简单，操作简便，价格相对较低，适用范围较广。2.5.1 取芯试验简述

在地面上进行竖向激震时，均会在其表面附近层状连续介质中产生瑞雷波，它的特点是能量大，传播速度低，频率低，随时间衰减慢，易于识别。在层状介质中，瑞雷波法具有频散特性，在同一地段求出一系列频率的瑞雷波速，就可得到一条瑞雷波频散曲线，不同波长的瑞雷波的传播特性反映了不同深度岩土介质的运动学特性，由频散曲线可以反演地下速度界面的分层厚度和速度结构，以确定每层岩土体的速度和深度参数。2.5.2 取芯试验评价实例总结

史慧杰[4]对青岛北海西湾造修船基地填海造陆区地基处理后采用了瑞雷波测试，其测试曲线反映了表层填石密实度不均匀，变化较大，6.2m以下波速逐渐增大，到11.2m波速变化减小，说明了随着深度增大，填石的密实度也增大，但到11.2m以下，波速突然变小，反映了1.2m进入了混合层；12m-12.9m曲线呈直线状态，波速不变，反映了12m-12.9m进入了淤泥层；12.9m以下波速急剧增大到452.5m/s，说明12.9m以后进入强风化基岩。钻探结果和面波试验结果基本一致。存在的问题

由于场地条件本身是复杂多变的，地基处理过程中由于方法的选择不同和施工过程的人为因素影响，将造成其结果有很大的差异，因此对地基处理效果进行检测就尤为重要。但是在实际操作过程中，由于各种方法的局限性和地下情况的复杂性，所以往往需要多中方法综合使用，达到相互验证的目的。同时，也要求我们不断探索，对已有方法进行完善并寻找新的更为有效的技术手段

With the rapid development of economy and technology in China, various construction projects started, but usually because of the particularity of geological conditions, the need for the construction site of the foundation reinforcement.The current application in the actual construction process of the foundation treatment method, preloading, dynamic compaction, reinforcement method, the replacement method vibroflotation, pile, jet grouting pile, soil improvement, but often due to human factors foundation treatment method of limitations and in the process of construction, resulting in uneven ground treatment effect.But a qualified engineering foundation, is an important guarantee for building design, construction quality and safety and therefore play an increasingly important role the detection effect of detection of reinforcement foundation.In current engineering application method in foundation detection processing are the main load test, dynamic penetration test, cone penetration test, ten plate shear test, wave velocity Test, core test and so on, but all kinds of test methods are limited in their own conditions, the accuracy of the test is very large.This paper combined with some engineering examples, the application and effect of these testing methods are discussed.2Test research on effect of foundation treatment

At present, many scholars have done a variety of research on the effect of the foundation reinforcement treatment, and discussed the advantages and disadvantages of various methods, this paper will be used in the following projects to elaborate and sum up.2.1 Static load test of foundation

Based on static load test is a kind of high precision, analysis the result is consistent with the actual well test method, the foundation bearing capacity determination and foundation settlement calculation is relatively accurate, but the cost is high, the strict technical requirements and test cycle is relatively long, generally large project site survey are required to perform the test.2.1.1 Static load test

Static load test simulation of foundation soil for buildings load conditions, loading on rigid bearing plate, uniform load transfer to the ground through the bearing plate, the deformation characteristics of Foundation Soil Determination of natural burial conditions, so as to assess the bearing capacity of foundation soil, settlement calculation of soil deformation modulus and deformation characteristics can be estimated based.The soil foundation reflects the more intuitive.The method for determining the bearing capacity of the foundation is: when the pressure ratio limit final settlement curve, the load ratio limit value corresponding to the load limit;when the load is less than 2 times the value of the corresponding proportion limit, half limit load value;when cannot be determined according to the above two requirements, desirable load s/b=0.01 corresponding, but its value should not exceed the maximum loading amount of half(Qian Gui.2012).2.1.2 Static load test evaluation Wang Wenkui(Wang Wenkui.2014), the I-steel and stacking pressure counter pressure system, with pressure platform force method is used to test the quality of a wharf along the Yangtze River land foundation treatment engineering.Square plate preloading foundation loading plate to the side of 1m, because of the engineering site foundation treatment design bearing capacity characteristic value is 120kPa, so the test of maximum load is 2 times the design value is 240kpa, according to 24kpa each stage of loading, and the settlement observation in the loading process, determine the characteristic value of bearing capacity of foundation.The test were tested in 20, the P-S curve can be seen, when the maximum load to 240kpa, all the measurement points are did not reach the limit state, the maximum settlement is 8.400mm, the minimum settlement is 6.200mm, according to the selection principle of the characteristic value of bearing capacity, half maximum load, which is 240kpa/2=120kpa to the point after the treatment of the foundation bearing force characteristic value, all The bearing capacity of the measuring point is satisfied with the design requirements.The project adopts the static load test to evaluate the foundation treatment, and shows that the ground treatment of the site has reached the foundation bearing capacity of the ground design 120kpa.2.2 vane shear test

Due to its own limitations, the vane shear test is generally used in the coastal areas of soft soil sites, and in some of the gravel soil can not be used to conduct the evaluation of the effect of ground treatment.2.2.1Brief introduction ofvane shear test Test, inverse clockwise rocking torsion box device small cranks, every 10 seconds to rotate one degree at a constant rate of rotation, when the test to peak or stable value, to test for 1min, test data, such as normal and record the peak data.According to the numerical calculation of undisturbed soil shear strength;complete shear strength determination, along the reverse direction continuous rotation of the probe rod coil 6, in accordance with the above steps operation, the determination of remolded soil undrained shear strength.2.2.2 cross plate shear test evaluation examples summary Wang Wenkui(Wang Wenkui.2014)Adopting vane shear test of along the Yangtze River a wharf land foundation treatment engineering quality detection.The experiment a total of eight holes, each hole 18 measuring points, on each hole detection data statistics, through with the original geological survey data are compared, the soil shear strength has been greatly improved, foundation treatment reached expected effect.2.3 light penetration test N10 light dynamic penetrometer for light penetration, their quality is light, simple equipment, widely used, easy operation, low cost and in a wide range of application in soft soil area.2.3.1Thelight penetration test The hammer blow energy, with probe, and the probe rod into the soil, according to the degree of difficulty of the penetration to evaluate soil properties, mainly used for grain filling and gravelly soil layer, and can be used for continuous penetration, in the test depth range continually measured soil mechanical properties and change rules(Qian Gui.2012).2.3.2 light penetration test evaluation summary Wang Wenkui et al.(Shi Huijie.2013)the light dynamic penetration test of along the Yangtze River a wharf land foundation treatment engineering quality detection.Site of 56 cement mixing pile top under the 2m range of pile head were measured.The experimental results show that the pile top under 2m every 30cm hammer hammer number is 64-78 hammer and design values: hammer N10>35 / cm2, uniform cement soil piles detection range, quality meet the design requirements.2.4 core test Core test is drilling and taking the foundation treatment of the foundation soil, and then carry out laboratory tests, in order to evaluate the effect of the foundation treatment, in some large-scale projects are more common.2.4.1 core test The application of jet grouting pile, vibro pile, mixing pile of foundation soil treatment site, on foundation pile core test, its purpose is mainly testing the quality of pile body concrete situation in, check the pile body concrete bonding conditions, stomatal, loose or broken pile;check the pile bearing stratum at the bottom of the geotechnical properties and thickness meets design requirement or standard, and check the construction record of pile length is real.2.4.2 core test case summary Wang Wenkui(Shi Huijie.2013)by taking the core test along the Yangtze River a wharf land foundation treatment engineering quality testing, completed a total of 16 cement mixing pile testing, core test and unconfined compressive strength group, 48, pile core sample molding average length of 8.5m, forming section of the core sample into short columnar fracture are in good agreement, pile body 8.30m post and core sample is not formed, has not formed the strength.Strength of core sample: completed a total of strength test group(n = 48, no side limit compression strength average value for 3.1mpa.Qian Gui(Qian Gui.2012)of Guangming Expressway Guangzhou section of soft foundation treatment of subgrade detecting core to check, the cores taken rate of close to 100%, the take rate 65.4%-74.4%.core sample continuous, complete, well cemented, a long column, concrete pile compressive strength represents value for 22.1Mpa that the soft soil foundation treatment to the foundation treatment design requirements.2.5 wave velocity test Wave velocity test is one of the common methods of foundation treatment, its equipment is simple, operation is simple, the price is relatively low, the scope of application is wider.2.5.1 core test Produced on the ground vertical shock, will in the near the surface of the layered continuous medium in which the Rayleigh wave, which is characterized by high energy and propagation speed is low, the low frequency with time attenuation is slow and easy to identify.In layered medium, Rayleigh wave method with dispersion characteristics in the same area for a series of frequency of the Rayleigh wave velocity can be obtained by a Rayleigh wave dispersion curves, different wavelength of Rayleigh wave propagation characteristics reflect the different depth of rock and soil medium kinematics characteristics, the dispersion curve inversion of underground velocity interface layer thickness and velocity structure, to determine each layer of rock and soil mass velocity and depth parameter.2.5.2 core test case summary Hui Jie Shi(Wang Wenkui.2014)on the West Bay of Qingdao Beihai made ship repairing base of sea reclamation area after foundation treatment by the Rayleigh wave test, the test curve reflects the surface filling stone compactness is not uniform, changes in the larger, 6.2 m below the wave velocity increases gradually, to 11.2 M wave velocity decreases, indicating that the with depth increasing, fill stone density also increases, but to 11.2 m below the velocity suddenly becomes small, reflecting the 1.2m in the mixed layer;12m-12.9m curve linear, constant velocity, reflect the 12m-12.9m into the silt layer;following 12.9 M wave velocity increases rapidly to 452.5m/s, that 12.9 m after entering the weathered bedrock.Drilling results and surface wave test results are basically the same.Existing problems Because the site itself is complex and changeable, foundation treatment process due to the method of selection of the different construction process of human factors influence, will cause the great difference, therefore on the foundation treatment effect detection is particularly important.But in actual operation process, due to the limitations and the subsurface complexity of various methods, so often need to more comprehensive method of use, to achieve the goal of mutual authentication.At the same time, it also requires us to constantly explore, the existing methods are perfect and looking for new and more effective technical means

学术报告之后的问答讨论环节（Question and Answer Session）是同行之间交流的良好机

会，双方可以针对报告中的具体问题进行探讨

（1）答问的方式与技巧

回答讨论环节可以让报告人通过互动及时地获得信息反馈并可以把在讨论中或得的建设性建议用于下一步的工作，因此对科研工作有很大的促进作用。对于如此重要的环节，报告人在报告之前应进行必要的准备，尽可能地保证这一环节完整、流畅地进行，一般应注意以下几点。

① 准备工作

学术报告中的提问者往往是相关领域中的专家，对报告的内容非常熟悉，因此所提出的问题可能会有相当的深度、广度以及不可预见性，有时甚至直接指出研究工作中的不完善之处或漏洞所在。由于时间关系，回答者在现场一般没有充分的时间进行考虑，这就要求报告人要事先进行充分的准备。在报告前，报告人应将对答环节的准备作为准备工作的一部分，进行深入考虑，全面的预测听众可能提出的问题，可以假设一些问题，并准备好最合适的解答。如果会议没有统一安排每个报告的问答环节，报告者在进行报告时就要预先告知听众随后的Q＆A Session，这样可以让听众为提问做好准备。

② 过程控制

在时间允许的情况下尽可能让每个想提问的人都有机会提问，不要让少数提问者的提问占据整个讨论环节，应按照提问者举手示意的顺序来请出提问者。在开始回答问题时，首先与提问者目光接触，然后转向其他所有听众，这样可以获得所有听众的注意。在回答完毕之后，可以再次通过目光了解提问者是否对回答表示满意。报告人应控制整个讨论的过程，对于与主题无关的问题可以礼貌地回避。

③ 答问方式

应首先仔细听清问题，在回答之前应将问题清楚的重复一遍，这可以保证对问题的正确理解，确保每个人都能听清楚问题，同时给自己一些时间来思考，表述答案前可做片刻停留，这既引起了听众的注意，又表明了对答案的谨慎态度，同时也给自己留更多的思考空间。不要对问题进行评价，避免说类似“That was a great question”的话，如果想要对某一问题进行肯定，可以用“Thanks for asking that question”或“I get asked that question by many people.”等中性的表述，还可以让听众感到平等。回答问题时应尽可能简洁，切题。在回答中应尽可能多地提及报告中的内容，这有利于听众对报告内容加深印象，并有利于控制问答环节的主题。

④ 问题的类型

对于寻求具体解释的一些问题，可以简单地重复报告的内容来对问题进行说明或证明，或是澄清听众的误解。如果提问者对报告内容提出不同见解，可以通过资料、事实、数据等来证明自己的观点，但一定注意态度要礼貌谦和。对于过于复杂的深层问题无法进行简单回答时，可以在简略回答之后邀约提问者在其他时间进行讨论。对于听众的评价或是建议应表示感谢，但要控制时间，适时地打断发言人并转入下一个问题。对不知道答案的问题应坦率的承认，不要回避或转换话题，并尽可能提供相关的书籍，资料或是该方面的专家以供参考。

⑤ 时间的把握

为了能够巧妙地结束回答问题环节，可事先准备一段总结性的陈述用来重申报告主题并结束问答环节。注意在达到规定时间时应立刻结束讨论环节，在回答最后一个问题之前们就要礼貌地表示即将超时，并可以让其他提问者将问题留在会后进行讨论。

⑥ 提问者的礼仪

大型会议中回答环节的时间往往比较短暂，提问者应抓住机会参与讨论，同时应注意以下方面。

如果为提问者准备了麦克风，则应在拿到麦克风后等待阿加安静下来在进行提问；大声地表述，让提问者和听众都能够听清楚问题；不必解释提问的理由以免浪费时间，但如果适宜可以需要地介绍自己（一定要简要）；对所提的问题应做好准备，以保证问题的有效性（不要提那些答案显而易见的问题）提问务必简短；每次尽量只提一个问题，把更多的机会留给其他听众。

第三篇：学术会议出国报告

赴新加坡参加亚洲泌尿外科年会小结

一、基本情况

第14届亚洲泌尿外科年会暨第30届新加坡泌尿外科年会于2016年7月20-7月24日在新加坡新达城会展中心举行，本次会议涉及泌尿外科肿瘤、泌尿系统结石、前列腺增生、泌尿专科护理等临床和基础研究等各个领域，内容丰富，精彩不断。

二、主要收获与体会

本次大会在2106年7月20下午设置了肾癌专场。在肾癌的综合诊治方面，大会热点如下：

首先是关于小肾癌诊治方面的一场辩论赛：来自新加坡总医院TAN Bien Soo教授的“积极监测或者介入干预治疗”PK 来自美国佛罗里达大学的Benjamin CANALES教授的“不要被大小欺骗”。TAN Bien Soo教授认为，对于年长、预期寿命较短的，和/或合并其它高危风险的临床疾病的患者，应采用主动监测方法。热消融治疗被证明不优于肾脏切除术或肾脏部分切除术。Benjamin CANALES教授则认为小肾癌可能具有更高的恶性度并且有高致死率，无法忽略的转移潜力。从局部复发率、肿瘤特异性生存率和无转移生存率三个方面看，肾脏部分切除效果优于冷冻疗法和消融术。

来自新加坡国立大学肿瘤研究所的Alvin Wong教授谈到转移性肾癌分子靶向治疗的10年回顾和反思。Alvin Wong教授认为：

1、在过去10年中关于进展期的肾癌治疗方面，靶向治疗的地位无可撼动。

2、近年来相继报道有疗效的免疫检测点抑制剂，给肾癌患者提供了一个全新的治疗方法（靶向免疫治疗）。

3、治疗毒性、成本和可获得性方面值得关注。

随后，本次UAA大会执行主席，来自新加坡伊丽莎白诺维娜医院Man Kay LI教授分享了关于肾癌静脉瘤栓手术疗效的分析。LI教授认为：

1、外科手术是最好的治疗方式，甚至在转移性病灶出现时也是如此。

2、团队密切合作、默契配合非常重要。

3、存活率取决于疾病的进展情况。

4、早期的肾癌伴下腔静脉癌栓具有较好的治疗机会。

最后，来自德国海德堡大学SLKKlinikenHeibronn医院的Jens RASSWEIILER教授汇报了关于腹腔镜肾脏部分切除术的经验和技巧——如何最小程度的缺血、最大程度的保留肾单位。谈及了5点经验：

1、腹腔镜或机器人采用经腹腔途径；

2、肿瘤靠近集合系统可置入D-J管；

3、肿瘤切除无需烧灼；

4、必要时缝合集合系统；

5、带刺缝线双层关闭。

三、下一步工作思路

本次UAA大会内容新颖、讨论热烈，使得每位与会代表对泌尿外科的临床微创手术治疗、分子靶向治疗、以及国际争议热点论题方面均有了一个全面系统的认识。他山之石，可以攻玉，在接下来的临床工作中，我也有如下思考：

1、目前在泌尿系肿瘤的综合诊治方面，微创手术还是绝对的主旋律，在**医院顺利引进达芬奇机器人手术系统之后，我们可以进一步发挥团队在泌尿系肿瘤尤其是肾癌微创手术方面的优势；

2、转移性肾癌的靶向治疗方面，我们需要进一步优化对患者的随访流程，有了自己的一手资料，才能在临床科研方面取得长足的进步；

3、对于整个泌尿外科团队而言，亚专科的分化是提高整个团队水平的重要举措。建设一个“分工明确，各有所长，团结写作，配合默契”的团队是我们下一步的工作方向。

第四篇：学术会议报告总结

中医思维在重症医学中的应用。ICU是重症医学科的临床基地，其对各种原因导致一个或多个器官与系统功能障碍、危机生命或具有潜在高危因素的患者，及时提供系统的、高质量的医学监护和救治技术，对病情进行连续、动态的观察，通过有效的干预措施，为重症患者提供生命支持，改善生存质量。通过对山东省中医院重症医学科孔立主任的授课学习，我了解到中医思维在重症医学中的应用。1注重整体观念，整体性体现在生理上、病理上、诊治上。2 中和思维 “中和”思想的核心是平衡与和谐，太过、不及对人体都是不利的。阴阳学说认为，正常情况下，人体的阴阳相对平衡协调意味着健康，《素问•生气通天论》中日“阴平阳秘，精神乃治”。针对疾病出现的阴阳平衡失调，治疗的原则是“损其有余，补其不足”，“谨察阴阳所在而调之，以平为期”。在某种意义上，耐心也是一种美德。过度的医疗干预反而对患者产生不利影响。3重视胃肠功能：胃气衰败为各种危重病的难点．亦提示预后不良。所以中医十分重视保护胃气。大肠小肠五脏皆属于胃，胃虚则俱病，说明胃虚导致疾病的发生。4未病先防，早期发现高危患者是预防和控制重症的基础，早期识别是防止病情恶化的重点，呼吸急促是早期最重要的独立预测指标。从急性肾损伤到急性肾衰竭，从急性肺损伤到急性呼吸窘迫综合征，都是渐进性的疾病发展，早发现、早诊断、早治疗。对ICU患者积极保护其胃肠功能，防治腹内高压综合征。治疗中应避免医源性脏器损害如肺损伤、肝损伤、肾损伤等。总之。ICU患者病情危重且复杂，病死率高。现代医学在生命支持方面具有明显的优势，如机械通气呼吸功能的支持，血液净化肾功能的替代治疗，抗生素针对病原菌的治疗。中医在这些方面虽然没有明显的优势，但针对炎症损伤、免疫损伤、胃肠功能、凝血功能损伤的修复具有明显的优势，进行环节的干预也是研究复杂性疾病的临床治疗疗效的有效方法。如何降低ICU患者病死率，提高患者生存质量，减少器官替代，降低治疗成本，是中医药亟待明确和解决的课题。在诊治危重病时要有整体观念、中和思维、重视胃肠功能、未病先防、早期识别意识，运用传统中医理论结合现代循证医学治疗危重病值得进一步研究。

另外，通过对其他专家的授课，我也在重症感染的抗生素应用原则、重症病人的镇静镇痛、重症病人营养新理念、重症创伤和凝血病、脓毒症新进展等方面有了更深的认识和提高，这对我在以后处理重症病人有很大的帮助和启发。

此次学习我受益匪浅，非常感谢院领导给予这次珍贵的学习机会，我将以我所学更好的应用到临床实践中，为医院/科室的发展做出自己最大的贡献。

第五篇：大数据学术会议报告

Big and Open Date ：Challenges for Smart City

Victoria Lopez

Victoria Lopez任教于西班牙马德里Complutense大学，其在计算机软件,计算机应用技术,计算机网络,人工智能,管理科学与工程等领域颇有建树，此次学术会议是她在2014年信息学与计算进展国际会议上的关于大数据的一次学术会议报告，她的演讲题目是Challenges for Smart City，以智能城市为研究对象，阐述大数据在智能城市领域内面临的挑战，鞭辟入里，发人深省，引人深思。

据她介绍，在1800年，全球仅有2%的人口居住在城市，到了1950年，这个数字迅速攀升到了29%。到2025年，城市人口预计将增加到20亿。当前全世界范围内的城市化进程大大加剧了气候变化、资源短缺和交通拥堵等问题，为人类城市生活带来一定的挑战。但同时智能城市建设面临诸多挑战：一是概念不清、外延不明。没有考虑到物联网、云计算、三网融合、无线宽带等新一代信息技术应用，仍然采用以前的技术思路和模式。二是进一步加剧了业务系统的信息孤岛局面，条块分割问题是全球信息化建设的顽疾。三是信息网络安全问题继续受到冷落。大量应用到物联网、云计算等技术，其信息网络安全问题将会更多。

既是挑战又是机遇，虽然面临问题较多，但是在大数据这个领域中，理论性的预见已经在相关行业成功实现，例如车联网，车联网促城市交通转型，随着车联网等新兴产业的兴起，智能交通已为世界各国在高新技术发展中争夺的一个重要领域。它加快了城市交通向低碳绿色交通的转型，是智慧城市建设不可或缺的一部分。大数据助力交通智能化，据介绍，在目前的城市交通体系中，公交、地铁、出租车以及公共自行车为主要出行方式，通过GPS定位、视频监控以及超声波传感等技术，在单一某个领域，智能交通已经进行了初步开发。比如，在某些公交站，乘客已经能提前预知下一趟公交到来的时间，乘客在打车时，通过部分手机软件已经能够查询到周边的空出租车，这些均基于一定的数据采集和分析。

她的中心思想在于，云计算要建平台，要有庞大的数据中心做支撑，其上是重要的关键业务的运营和服务，而大数据就是构建在云平台上的一种‘杀手锏’的应用，云计算是一个全新的时代，和PC时代完全不同。如何将我们的文化，我们的技术和业务模式更快的转移到云计算，构建起生态系统将是最大的挑战。虽然很高兴已经有了一些发展，但是还需要相当长的过程才能实现。

从此次学术会议报告中我学到了如何听取报告的相关主旨和核心思想，在这次报告中也体会到了西方学者和本国学者思考问题的异同点，当然更需要的是加强英语学习能力和本专业的学习能力。
