摘要

应用力学原理从理论上分析了大型高速滑坡岩体与阻挡山体的碰撞过程，得出了碰撞后滑坡岩体的平均运动速度和运动方向的关系式；通过碰撞试验研究了滑坡岩体碰撞解体后的加速运动效应，得出了不同速度段岩体体积的分布规律，为进一步研究远程活动阶段碎屑流的形成奠定了基础，对防灾减灾具有重要意义。

Abstract

The impact process of a large-sized high-speed landslide against the mountain body is analyzed theoretically with mechanical principles. A then the expression of average velocity and moving direction of the landslide rock-mass after impact are obtained. Through the impact experiments

the effect of acceleration motion of partial rock mass after impact is also studied. Finally

the volumetric distribution law of various segments with different velocities after impact is obtained. The results will be useful for reducing and preventing disasters.
