高速公路滑坡治理工程设计方案VIP免费

##大学毕业设计成雅高速公路K26+200滑坡治理工程设计作者姓名：李国忠学号：20102911专业：土木工程指导教师：刘尊稳【摘要】本设计以成雅高速公路K24滑坡勘察报告为依据，分析了滑坡的工程地质条件及基本特征。在此基础上研究了影响滑坡失稳的因素，进而分析了滑坡的成因机制。然后对滑坡的稳定性进行了定性评价，并采用极限平衡原理和传递系数法，计算出滑坡的稳定性系数和滑坡推力，对滑坡稳定性进行了定量评价。在此基础上提出了两种治理方案，按照“经济合理，工期短，工程技术可行，治理效果安全可靠”的设计原则，从中选取了抗滑桩+排水工程+削坡反压+路面路基恢复的治理方案，对滑坡做了治理设计。【关键词】滑坡；稳定性；治理设计；抗滑桩；排水工程成都理工大学毕业设计II##大学毕业设计ThepreventiondesignofthetheChengyahighwayK24landslideName：ZhaoHechuanStudentNo.：200403010405Major：CivilEngineering（GeotechnicalEngineering）Supervisor：WangXiaoqunAbstract:Basedonthegeo-technicaldataoftheChengyahighwayK24landslide,thegeologicalconditionaboutthelandslidewasstudied,thenthefactorswhichtamperedwiththeslope’sstabilitywereconstrued,thereasonswhichcausedthelandslidewereanalyzedandthelandslide’sstabilitywasestimated.Accordingtotheunbalancethrusttransmissioncoefficientmethod’sprincipleandsupposition，thelandslide’sstabilitycoefficientwascalculated.Thenthelandslide’sstabilitywasappraised.Basedontheanalysis,twotreatmentmeasureswereadvanced.Accordingtotheresultoftheslopestabilitycalculation,thedesignprinciplewasthattheprojectcostwasreasonable,timelimitfortheprojectwasmuchless,thetechniquewaspossibleandtheprojectwassimpleandeasytoconstruct.Finally,areviseddesigningprogramhasbeenchosen,whichincludedanti-slidepile,drainageworksandexcavatingtheslopandbackfillingthesoil.Atlast，theslope’sdesignationofremedyingengineeringwasmade.Keywords:landslide,stability,anti-slidepile,drainageworks兰州交通大学博文学院毕业论文（设计）目录第1章前言.......................................................11.1选题依据及其意义............................................11.2滑坡治理主要方法研究........................................11.3设计依据及设计思路..........................................21.3.1设计依据..............................................21.3.2设计思路..............................................21.4本次设计主要成果............................................3第2章滑坡区自然地理及工程地质条件................................52.1自然地理条件................................................52.1.1地理位置..............................................52.1.2气象水文..............................................52.2滑坡工程地质条件............................................52.2.1地形地貌..............................................52.2.2地层岩性..............................................62.2.3岩土体的物理力学性质..................................72.2.3地质构造与地震效应....................................72.2.4水文地质条件..........................................7第3章滑坡基本特征................................................93.1滑坡的基本特征..............................................93.2滑坡变形特征................................................93.3滑坡体结构特征..............................................93.4滑带及滑床结构特征.........................................103.5滑坡成因机制分析...........................................123.5.1影响因素.............................................123.5.2成因机制...................
