毕业设计（论文）中文题目：某软土地区铁路线路路基设计学院：北京交通大学专业：土木工程姓名：学号：指导教师：2017年11月5日远程与继续教育学院摘要本设计的主要内容是根据软土地基的工程特点，结合客运专线路基设计规范针对铁路客运专线软土地基上路堤的设计与施工。首先，提出了两种软土地基加固方案，CFG桩和袋装砂井，采用条分法和分层总和法对路基分别进行稳定性检算和沉降计算,并对它们进行经济技术比较，最后提出减少工后沉降的措施。其次，对路堤边坡进行了稳定检算，设计了路基的填筑方案，提出了保证路基基床压实度的措施。最后提出了路基变形监测方案。设计成果满足相关客运专线的规范要求,设计方案和施工方法是比较合理的。关键词：客运专线；软土地基；稳定检算；工后沉降；变形监测AbstratThemainelementsofthisdesignisbasedontheengineeringcharacteristicsofsoftsoil,combinedwithsubgradedesignspecificationsforrailwaypassengerdedicatedsoftdesignandconstructionofembankment.First,weproposetwosoftsoilreinforcement,CFGpileandSandWick,stratifiedbyslicesummationmethodandthestabilityoftheroadbedwerecheckingcalculationandsettlement,andtheirtechnicalandeconomiccomparison,thefinalproposedmeasurestoreducethesettlementafter.Secondly,ontheembankmentslopewasstableandcalculationofthedesignoftheembankmentfillingprogram,proposedtoensuremeasuresofdegreeofcompactionofsubgradebed.Finally,theroadbeddeformationmonitoringprogram.Designresultstomeetregulatoryrequirementsrelatedtopassengerline,designandconstructionisreasonable.Keywords:passengerdedicatedline；softsoilfoundation；stabilitycalculation；post-constructionsettlement；deformationmonitoring目录第1章绪论..........................................................................................................................11.1软土的定义、特点与工程特性.................................................................................11.1.1软土的定义及特点...............................................................................................11.1.2软土的工程特征：...............................................................................................11.2国内外客运专线路基工程处理方法........................................................................11.3国内外软土地基主要处理方法.................................................................................11.4我国新建客运专线路基对软土地基的要求.............................................................21.5课题研究的主要内容.................................................................................................2第2章客运专线路基横断面设计.....................................................................................32.1路堤横断面设计.........................................................................................................32.1.1断面设计原始资料..............................................................................................32.1.2路肩宽度设定.......................................................................................................32.1.3边坡坡率..............................................................................................................32.1.4填料选择..............................................................................................................32.1.5线间距..................................................................................................................32.1.6路基面宽度确定............................................
