滑坡是一种常见和重大的地质灾害,不仅给人类的生命财产带来重大威胁,也对许多工程建设造成了严重的影响。本文以江西洪屏抽水蓄能电站交通洞口边坡整体失稳为例,以平面二维分析为主,对不加锚索,不加外部荷载的情况和有锚索且有外部荷载的情况分别计算安全系数。且在计算时对边坡处于天然状态,无加固;边坡处于天然状态,有锚固;边坡处于锚固状态,有暴雨,无地震;边坡处于错固状态,无暴雨有地震等4种工况进行了分析,分析方法以极限平衡法为主,确定边坡开控与支护方案,以有限元强度折减法为辅,进行边坡稳定性复核分析。
Landslide is a common and major geological disasters, not only pose a significant threat to human life and property, but also have a serious impact on many construction projects. In this paper, the overall instability of the slope at the traffic entrance of Hongping pumped storage power station in Jiangxi Province is taken as an example. The plane two-dimensional analysis is taken as an example. For the cases without anchor cables, without external load and with external load, Calculate the safety factor. In the calculation, the slope is in a natural state without reinforcement; the slope is in a natural state with anchorage; the slope is in an anchored state with heavy rainfall and no earthquakes; and the slope is in a solid state with no rainfall and earthquakes The analysis and analysis methods are based on the limit equilibrium method, and the program of open-circuit control and support of the slope is determined. Based on the finite element strength reduction method, the stability analysis of the slope is carried out.
