摘 要: | 以海州露天矿地质背景条件为基础,从边坡滑动形成的影响因素分析出发,研究北帮边坡滑动成因机制,确定边坡的滑动破坏模式。同时,以该边坡的典型工程地质剖面为基础,构建稳定性计算的地质模型,并采用极限平衡法——简布法、摩根斯坦-普利斯法、推力系数法等进行边坡稳定性分析,用以说明北帮边坡的整体稳定性,为滑坡治理提供科学合理的设计依据。

ANALYSIS OF SLIDING MECHANISM AND STABILITY OF THE NORTHERN SLOPE HAIZHOU OPEN-PIT COAL MINE |
| |
Abstract: | This paper,based on the geological background conditions of Haizhou open-pit mine,from the analysis of the influence factors for causing slope sliding,researches on the sliding mechanism of the northern slope and determines the sliding failure mode of the slope. At the same time,on the basis of the typical engineering geological profile of the slope,the limit equilibrium method such as Janbu method,Morgenstern-Price method,thrust coeffi-cient method etc is used to analyze the slope stability,in order to explain the overall stability of the northern slope,and to provide a scientific and reasonable design basis for the slope treatment. |
