摘要

以丰都名山崩滑体为研究对象，拟通过对该崩滑体失稳破坏过程的离散元模拟分析，达到对该崩滑体的稳定性进行有效分析评价的目的。研究结果发现，崩滑体的滑移崩塌过程及散落情况与其坡脚是否风化剥蚀相关，且不论坡脚是否风化剥蚀，其上部块体的运动轨迹与中下部块体的运动轨迹存在着明显差异。分析结果同时还表明，丰都名山崩滑体的确存在滑移崩塌危险，应积极采取适当防范措施。

Abstract

This paper hopes to reach the purpose to effectively evaluate the stability of the rockfall through the simulation of Fengdu’s Mingshan rockfall by discrete element method. We have discovered that the destructive process of the rockfall is contact with the bottom denude degree of the rockfall

and whether the bottom of the rockfall is denude or not

the mobile track of the top blocks is different from the other blocks. The results show that the Fengdu’s Mingshan rockfall is danger in truth

and must take a certain method to protect it from collapsing.
