波西村滑坡成因分析及治理方案设计 作者：彭博 学号：200803010235 专业：土木工程(岩土工程方向) 指导老师：吴礼舟 摘要 由于地震及暴雨作用，攀枝花市仁和区平地镇波西村发生大型滑坡。经初步调查，目前该滑坡处于蠕动变形状态，在暴雨作用下，该滑坡有大规模下滑并伴生泥石流的可能性。其整治十分必要。现对波西村田房滑坡进行详细的调查，收集区域的地质环境条件、滑坡的基本特征、主要影响因素。在此基础上，分析了滑坡的成因机制和变形破坏机理，进行了滑坡稳定性分析和校核，确定了滑坡的治理设计推力值，对滑坡进行了定量评价。针对调查期间波西村田房滑坡的变形加剧状况，提出了两种治理方案，经过方案比较，拟采用地表裂缝处理-截排水工程-支撑渗沟-抗滑桩支挡的治理方案。 关键词 土质滑坡；治理设计；滑移拉裂；地表裂缝处理；截排水工程；支撑渗沟；抗滑桩 The analysis and treatment design of the boxi village landslide Name: Peng Bo Student No: 200803010235 Major: Civil Engineering (Geotechnical Engineering) Supervisor: Wu Lizhou Abstract: As a result of earthquake and rainstorm a large-scale landslides in Boxi Village of Pingdi stown of Renhe District happened. After preliminary investigation, the landslide has been in the stage of the creep deformation. Under the action of heavy rain, the landslide will possibly initiate and transfer into debris flow. Controlling engineering design is necessary. The geological environments of the landslide, geological characteristics of the accumulation and the main influencing factors are investigated. Based on this, its deformation and failure mechanism are discussed, and the stability is checked and computated, the design value of the accumulation thrust are determined so as to assess landslide quantitatively. For deformation increased status the landslide in Boxi village during the survey period, treatment projects have been proposed. After the designing of screening, a comprehensive controlling designing program has been taken to stabilize Boxi village landslide in the form of surface cracks treatment, cut and drainage works, support blind drain, and the anti-slide pile retaining treatments. Key Words：Boxi village landslide; soil landslide; surface cracks treatment; cut and drainage works; supporting blind drain; the anti-slide pile 目录 第1章 前言 7 1.1选题依据及研究意义 7 1.1.1任务概况 7 1.1.2选题依据 7 1.1.3研究意义 8 1.2 国内外滑坡研究现状 8 1.2.1 滑坡稳定性研究现状 8 1.2.2 抗滑桩研究现状 12 1.3 研究整体
