滑坡失稳后变形过程分析

On analysis of deformation process after stability loss of sliding slopes

针对滑落体滑动过程的速度和变形的不均匀性、变形能的积累与释放以及滑体与滑床的摩擦等,建立了滑落体运动的弹簧滑块模型,分析了滑块运动过程,结果表明:该模型通过数值方法可以计算滑落体滑动全过程的变形,同时可以计算滑落体每一条块在滑动全过程的速度和变形以及滑落体的滑动时间和最大运动距离。

Aiming at the sliding speed of the sliding bodies,the unevenness of the deformation,the accumulation and explosion of the deformation force and the friction between the sliding body and the sliding bed,establish the spring block model of the sliding body,the paper analyzes the sliding movement process,and proves that the model can calculate the deformation in the whole sliding process by the numerical methods,the speed and deformation of every piece of the sliding body,the sliding time,as well as the maximum movement distance.
