清华大学综合论文训练题目:我国山区机场高填方地基处理工程综述及数据库研发系别:土木工程系专业:土木工程专业姓名:李鹏指导教师:宋二祥教授2008年6月18日中文摘要随着我国经济的持续发展,特别是西部大开发战略的实施,西南地区机场建设将进入迅猛发展阶段。这些机场工程的特点是场区地质条件复杂、填方高度大,不少还处于高地震烈度区。对这种山区机场的大面积高填方地基,其稳定和沉降控制是地基处理工程的核心问题。我国目前已建成的山区高填方机场有九寨黄龙机场、万州机场、攀枝花机场、龙洞堡机场等近二十座。了解这些已有工程的地基处理施工方法和地基处理效果检测技术无疑有着重要的参考作用。因此,收集整理我国已有山区高填方机场地基处理案例并开发相应的数据库管理系统,对已有的机场高填方地基处理资料进行管理,有着十分迫切的需求。本文以山区机场高填方地基处理案例库信息管理系统的设计与实现为主要内容,对案例库信息管理系统的总体设计、数据库的设计与建立、系统管理功能的实现进行了全面的论述,进而初步建立了一个高填方机场案例库。同时,本文通过大量的文献调研,收集整理了我国已有山区机场高填方地基处理的几乎全部工程实例,并对所采用的地基处理方法进行了归纳和分析。本文的主要成果如下:(1)从数据库基础理论出发,根据山区机场高填方地基处理工程案例的特点设计数据结构,基于MicrosoftAccess数据库,运用关系数据模型建立了机场案例数据库,并将目前收集整理的机场数据录入数据库。(2)运用VisualBASIC及MicrosoftAccess数据库内置宏语言开发案例数据库信息管理系统,实现了对数据的输入与更新维护、数据信息查询、报表输出等功能。(3)结合国内已有山区机场高填方地基处理工程实例,围绕地基稳定及沉降控制这条主线,综述了已有工程中原地基、填筑地基处理的施工要点以及目前已有的地基处理检测技术。关键词:地基处理高填方数据库MicrosoftAccess山区机场IABSTRACTWiththecontinuousdevelopmentoftheeconomyofChina,especiallywiththeimplementationofthegreatdevelopmentstrategyforWestChina,airportconstructionsinthemountainoussouthwestofChinaentersintoaprosperousperiod.Complexgeologicalconditions,hugeheightoffilledground,highintensityofearthquake,arethemaincharacteristicsfortheseairports.Therefore,howtoensurethestabilityandlimitthedeformationofthehighfilledgroundoflargeareaisthefirstandprimaryissueintheseprojects.Therearealmosttwentyairportsinthemountainousareawithhigh-filledgroundthathavebeencompleted,suchasJiuzhai-huanglongairport,Wanzhouairport,Panzhihuaairport,Longdongbaoairportandsoon.Itisofgreatvaluetounderstandtheconstructionmeasuresforthegroundtreatmentaswellasmethodsofqualityinspectionoftheseprojects.Soitisquitemeaningfultodevelopadatabaseandcorrespondinginformationmanagementsystemforthetreatmentofhigh-filledgroundofthesecompletedairportprojects.Thethesisfocusesmainlyonthedesigningandimplementingoftheinformationmanagementsystemforthedatabaseofgroundtreatmentofmountainoushigh-filledairportcases,detailingtheoveralldesignoftheIMS,databaseestablishmentaswellastheimplementationoffunctionsontheinformationmanagement.Furthermore,throughalargeamountofliteratureresearch,analysisofthegroundtreatmentmethodsofseveralhighfilled-upairportprojectsthatarealreadycompletedhasbeenalsodiscussed.Themainresultsarethefollowing:(1)Todesignthedatastructureaccordingtothefeaturesofmountainoushigh-filledairportcasesonthebasisofthedatabasetheory.FoundonMicrosoftAccessdatabase,thegroundtreatmentofmountainoushigh-filledairportdatabaseissetupbymeansoftherelationshipdatamodel,andthendocumentedcasedataareinputintothedatabase.(2)TodevelopthedatabaseIMSwithVisualBASICandMacroLanguageprovidedbyMicrosoftAccessdatabase.Inthissystem,functionsaremadeavailabletoinputandrefreshthedata,searchthedatainformation,outputthereportforms,etc.III(3)Basedonseveralhighfilled-upairportprojectsthatarealreadycompletedinChina,followingthemainlineofcontrollingstabilityandsettelmentofhighfilled-upground,treatmentmeasuresoforiginalgroundandhigh-filledgroundaswellasmethodsforqualityinspectionarepresented.Keywords:groundtreatmenthigh-filledDatabaseSystemMicrosoftAccessairportinmountainousregionsIV目录第1章绪论...................................................................................................................11.1引言........................................................................................................................11.2国内研究现状........................................................................................................21.3研究的目的及意义................................................................................................41.4研究内容及技术路线............................................................................................51.4.1研究内容...........................................................................................................51.4.2技术路线...........................................................................................................6第2章文献调研工作介绍...........................................................................................92.1工程地质情况......................................................................................................102.2实际施工方案......................................................................................................112.3地基处理现场试验研究......................................................................................112.4离心机模型试验研究..........................................................................................122.5大三轴试验研究..................................................................................................142.6沉降与稳定性分析..............................................................................................152.7曾发生过的工程事故..........................................................................................172.8小结......................................................................................................................18第3章我国已有山区机场高填方地基处理方法的汇总分析.................................193.1高填方原地面土基处理......................................................................................193.
