【摘要】 滑坡是各种地质灾害中频率最高、损失最大的灾害类型。以四川阆中市某一滑坡为例,为了弄清不同因素对滑坡影响大小,利用数理统计分析的方法,选取4个主要影响因素进行了敏感性分析。根据分析,滑坡体的内摩擦角对滑坡的稳定性产生的影响最大,其次是内聚力、地震力和饱水比。通过敏感性分析,对该类型滑坡的治理设计提供理论依据,具有一定的实际意义。更多还原

【Abstract】 The landslide is the most frequently in a variety of geological disasters,and the loss is the biggest.Take the landslide in Langzhong Sichuan province for example,in order to find out the different factors which influence the landslide,using the method of mathematical statistics analysis,and selected four main influence factors for sensitivity analysis,according to the result of analysis,the internal friction angle produce the biggest influence of the landslide stability,cohesion,earthquake force and saturated ratio are the secondary.Through sensitivity analysis,it is provided a theoretical basis for this kind of landslide′s control design,and which also have a certain practical significance.更多还原
