摘要
降雨对滑坡的激发作用是个广泛讨论的话题。从决定滑坡稳定性的物质条件、结构条件和影响滑坡稳定性的环境条件及雨强、降雨量、降雨入渗、土体力学性质改变等多个方面阐述降雨对滑坡的作用过程。并进行大型的野外人工降雨激发滑坡试验和室内土工试验 ,试验结果表明粘聚力和内摩擦角与含水率呈线性递减关系 ;
The effect of rainfall on landslide is a widely discussed topic.This paper expatiates the process of the action between the rainfall and landslide from some aspects such as the substance conditions and structure conditions that determine the stability,environmental conditions that affect the stability,rainfall,rainfall infiltration,rainfall density,and the variation of mechanical properties of soil,etc. We have accomplished the large scale field test of landslide inspired by artificial rainfall and laboratory soil test.The test results illustrate that there is a linearly descending relationship of the cohesion and angle of internal friction with the water content.The landslide inspired by rainfall mainly and other factors is a complex process.
