本文以洒勒山滑坡作为典型实例,扼要地探讨了高速远程滑坡的形成条件和运动规律,提出了一种冲击性碰撞作用机理和连续可变的块体运动理论,初步建立了一套系统地阐述高速远程滑坡发生机理和运动机理的理论及数值模拟方法。
The formation conditions and movement principles of high speed and long distance landslide were briefly researched by analysing its formation procedure and mechanical origin on Saleshan landslide as a typical example in the present paper. Progressively it made sure the probability of four section shaped occurrence mechanism of high speed and long distance landslide in which there were the relative locked section in the latter, the relative stable section in the former, the creep sliding section in the middle and the tension crack section at the top of slope (three section were usually divided before). And especially combining with the movement characteristics of Saleshan landslide, worked out the movement mechanism model of high speed and long distance landslide, and presented the impulsive bumping action and the mass movement theory with continuity and variety. What is more, a satisfactory computer simulation was carried out for the movement procedure and principle of Saleshan landslide. Therefore, initially founded a set of mechanism theory and numerical simulation method to describe sysmatically the occurrence mechanism and movement mechanism for high speed and long distance landslide.
