大气降雨对滑坡体的含水量和容重均有影响 ,该影响具有一定的时间进程 ,同时滑坡滑带土的含水率对内摩擦角和内聚力均有一定的影响。本文提出了滑坡启动的两种不同机制。通过降水滑体含水率滑体容重、滑带土内摩擦角、内聚力以及它们与滑坡稳定系数的定量关系及其时间效应 ,建立起滑坡启动的速度、推力、方向和启动时间的预测、预报模型。同时在GIS支持下完成滑坡启动机制的数字仿真
Atmospheric rainfall has an impact on the water content and bulk density of the landslide body, and the influence has a certain time course. At the same time, the water content of landslide soil has some influence on the internal friction angle and cohesion. This paper presents two different mechanisms for landslide initiation. The prediction and prediction model of the speed, thrust, direction and start-up time of landslide start-up are established through the quantitative relationship between the water body weight of the landslide and the bulk density of the landslide, the friction angle and cohesion of the soil in the landslide, and their quantitative relationship with the stability coefficient of the landslide. . At the same time, the digital simulation of landslide start-up mechanism is completed with the support of GIS
