The FLAC simulation model was established for layered rock slope in the upper plate of Anqian Xu Donggou Mine .It described the anisotropic characteristics of layered rock mass by using Ubiquitous-Joint Model .The mining simulation was adopted to analyze the variation rules of stress and displacement .Then the distribution situation of the plastic zone was confirmed .The simulation result shows that the stability is reduced and the possibility of landslide along the bedding is increased because of the Consequent rock mass .%采用节理化本构模型描述层状岩体的各向异性特征，对鞍千矿许东沟采场上盘顺层岩体边坡建立了FLAC计算简化模型，数值模拟分11步进行开挖，分析计算在开挖过程中岩体内部应力与位移的变化规律，确定边坡岩体塑性区的分布情况。模拟结果表明层状岩体边坡的稳定性在岩体强度和结构面强度共同控制下，由于大量顺层层理的存在，降低了岩体边坡的稳定性，增大了沿层理形成滑坡的可能性。
