| 摘 要： | 堆积体位于四川某公路K43+040-K43+210段岷江左岸,其物质组成主要是后缘基岩崩塌形成的粒径较大的块体,架空现象明显。特殊的物质组成及其结构特征使得采用传统稳定性评价方法评价其稳定性时面临诸多问题。本文在大量野外现场调查的基础上,分析研究了堆积体的形成机制、坡体结构特征,在此基础上,运用离散元方法分析了堆积体开挖后的变形破坏特征及其运动过程,同时采用定性和定量相结合的方法对堆积体的稳定性进行了综合评价。

| Abstract: | A falling accumulation lies in the K43+040-K43+210 segment of a road, some big blocks falling from the bed rock back of the accumulation mainly compose it. In this paper, the accumulation's mechanism of formation and it's characteristics of structure are studied base on field investigation, and the accumulation's characteristics of failure and deformation after being excavated with the discrete element method are studied, and the accumulation's stability is also evaluated with qualitative method and quantitative method. |
