摘要 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 brings a major threat to human life and property,but also causes serious impact to many construction. This paper researched slope instability of traffic tunnel entrance with limit equilibrium method and strength reduction FEM method. The stabilities of 4 conditions are analyzed and checked in this paper. That are slope being in natural state without reinforcement,slope being in natural state with reinforcement,slope being reinforced with heavy rain and without earthquake,slope being reinforced without heavy rain and with earthquake.
