山区地下槽仓边坡稳定性评价

On slope stability evaluation of underground trough and bunker in mountainous areas

针对平朔东露天煤矿产品煤槽仓岩土特征,利用极限平衡法对开挖后的边坡按天然、降雨、地震以及地震和降雨同时作用的四种工况进行了模拟,并进行稳定性评价,从而为槽仓边坡的治理及合理监测方案的制定提供了依据。

According to the rock features of the product coal troughs and bunkers of Ping-Shou Eastern Open-pit Coal Mine, the paper under- takes the simulation for the four situations of the slopes affected by natural influence, the rainfall, the earthquake and the common influence of the earthquake and rainfall by adopting the limit equilibrium method, and has the stability evaluation, so as to provide the reference for the treat- ment of slopes with the trough and bunker and the reasonable establishment of the supervision schemes.
