中文摘要：以新疆准东露天煤矿非工作帮缓倾顺层泥质边坡失稳破坏为研究对象,首先对非工作帮滑坡特征和工程地质条件进行分析;然后按照破坏特征将滑坡体分为A、B、C 3个区域;最后,在滑坡体上选择典型断面,采用SIGMA/W模块对不同坡顶排土场堆置高度条件下的边坡稳定性进行数值模拟计算。计算结果表明,随着坡顶排土场堆置高度的不断增加,非工作帮470 m平台以上的剪应力显著集中,并得到坡顶排土场堆置对缓倾顺层泥质边坡稳定性影响规律。

外文摘要：Taking Xinjiang opencast research object. First, analyze the coal nonworking gently inclined characteristics and engineering bedding mud slope failure as the geological conditions of the non working group. Then the landslide body is divided into three areas： A, B and C according to the failure characteristics. Finally, select the typical section in the landslide body. Using the SIGMA/W module on numerical simulation of the slope stability under the condition of dump slope with different stacking height. Calculation results show with the top of the dump heap height increasing the shear stress significantly concentration of non working 470 m platform. And get the top dump on the gently inclined bedding slope stability influence of mud which provide scientific basis for the design of landslide control and early warning.
