| 摘 要： | 降雨对滑坡的激发是广泛讨论的话题，从物质成分，结构构造和雨强，降雨量、土体应力特征等方面分析滑坡频发的原因，进行大型人工降雨 滑坡试验，观测降雨激发滑坡的过程，室内土工实验表明内聚力和内摩擦角与含水量之间有突变现象，松散砾石土斜滑坡是在以降雨为主导因素的多种因素综合作用下发生的。

| Abstract: | The effect of rainfall on landslide is a widely discussed theme. This paper expatiates the inspiring cause from some aspects such as the substance composition,structure conditions,rainfalls,rainfall density and the stress characteristics etc. We have observed the course inspired by artificial rainfall from the large outdoor landslide experiment. The indoor experiment illuminates that the cohesion and inner friction angle have a chop relationship with the moisture content. The gravel slope landslide is inspired by many factors of which the rainfall is the dominant. |
