基于对高速滑坡发生机理的认识及对其运动特征和堆积特征的分析 ,认为滑体内部的速度和变形具有不均匀性 ,且运动过程伴随着变形能的积累、释放和损耗。在此基础上 ,假定滑体的运动形式是连续可变的 ,建立了预测高速滑坡远程的块体运动模型。应用该模型可以模拟滑坡发生后滑体运动的全过程 ,同时可预测滑坡的最大滑速和最大滑距。利用该模型对洒勒山滑坡等实例进行了数值模拟 ,结果和实际基本相符 Based on the recognition of the mechanism of high-speed landslide and the analysis of the characteristics of its movement and accumulation, it is concluded that the velocity and deformation of the slide body are inhomogeneous, and the movement process is accompanied by the accumulation, release and loss of deformation energy. On this basis, assuming that the motion of the slide body is continuously variable, a block motion model for predicting the long-range high-speed landslide is established. The model can be used to simulate the whole process of landslide movement and predict the maximum slip and the maximum slip of the landslide. The model is applied to the numerical simulation of the Sailleshan landslide and the results are in good agreement with the actual ones
