摘要
针对辽宁省抚顺市西露天矿南帮滑坡问题,在地质环境综合调查的基础上,分析该滑坡特征,用改进的传递系数法和Sarma法对地表变形较为严重的E400剖面和E1200剖面的稳定性进行分析,用层次分析法对滑坡进行整体稳定性分析,从而对滑坡稳定性做出综合评价.结果表明:E400剖面和E1200剖面处于变形滑动阶段,滑坡处于不稳定状态.
Based on investigating the geology environment of the south landslide of Fushun west open pit mine in Liaoning province, the characteristic of the landslide was analyzed. The stability of the E400 and the E1200 profiles which already had serious ground deformations were analyzed by the modified transfer coefficient method and the Sarma method. The stability of the whole landslide was analyzed by the analytic hierarchy process. In the end, the stability of the whole landslide was evaluated. The results show that the E400 and the E1200 profiles are in the sliding and deformation state, the whole landslide is in the unstable state.
