分析了从静态到动态的滑坡运动过程 ,建立了滑坡动态滑动面和瞬间稳定系数的概念 ,分析了滑坡运动过程中瞬间受力状况、运动方向和速度变化 ,进行了滑坡运动速度、力、运动方向及时间关系的定量描述。最后 ,在GIS支持下完成了滑坡在三维空间中运动过程的数字仿真

The conceps of dynamic gliding plane and instantaneous stability coefficient of landslide are established through analyzing landslide motion process from static state to dynamic state. The relationship of velocity, force, direction of landslide motion and time is quantitatively described through analyzing the instantaneous stress state, velocity variation and motion direction of landslide. At last, the digital simulation of 3 dimension motion of landslide is accomplished under GIS support.
