| 摘 要： | 曼家寨矿区兴发露天采场东帮边坡已经发生滑坡,随着时间的推移有逐渐加大的趋势.分析了各种内在因素和外在因素对曼家寨寨露天采场东帮滑坡的影响,采用极限平衡法中的Bishop法从二维的角度对现状边坡进行稳定性计算,其稳定性系数小于1,经过处理方案的比选论证,提出了适合滑坡现状的防治对策,采用坡脚反压加固处理后,稳定性系数为0.97-1.05,边坡依旧不稳定,采取辅助加固措施二次坡脚反压后,边坡处于稳定状态.

| Abstract: | Landslide is occurred in the east Xingfa open pit of Manjiazhai mine,and gradually getting increase as time goes on.After analyzing impacts of various internal and external factors on east of Xingfa open pit at Manjiazhai mine,calculated stability coefficient of slope was from 0.74 to 0.85 by the Bishop method of the equilibrium method from two-dimensional perspective.Status of landslide prevention measures were proposed after through the choice and demonstration of several solutions.Stability coefficient w... |
