摘要
以西南地区某公路滑坡为例,采用离散元方法研究得出了其滑动机制具有典型的滑移—拉裂—剪断"三段式"机制特征,利用传递系数法进行滑坡稳定性计算,从而设计出抗滑桩方案和抗滑桩+前缘弃渣填筑方案,最后经过各方面的比较,得出了抗滑桩+前缘弃渣填筑为本滑坡治理的最优方案。
A road landslide in southwest region of our country is studied and a typical sliding mechanism with three stages of slip-pulling apartcutting through is found by using the distinct element method. Then transfer coefficient method appointed is used to analyze the stability of the landslide and two design schemes of slide-resistant pile and slide-resistant pile with frontal zone filling with waste slags are proposed for controlling the road landslide. Finally,after comparison,the latter scheme of slide-resistant pile with frontal zone filling with waste slags is chosen for the best treatments for the landslide.
