Abstract

Abstract: In the paper,the relations of the transferring and translating of energy while high-speed landslide rockmass impact immobile roadblock are analyzed in detail.The expressions of the distributive energy when landslide ro ckmass fall to pieces,and the average velocity and direction after impacting are putted forward. All of those establish a base to study the formation of debris flow,and are important to reduce and prevent disaster.

Key words: high-speed landslide, impact, energy, analyses, rockmass

摘要： 笔者在文中对高速运动的滑坡岩体与途中山体发生碰撞时能量的传递及转化关系进行了详细分析,得出了滑坡岩体解体破碎时可分配能量的表达式及碰撞后滑坡体的平均速度和运动方向,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.
