摘　　要：贵州省凯里市龙场镇渔洞村岔河组老山新村同一位置先后2次发生崩塌灾害,崩塌堆积体灾害导致5人死亡,掩埋6栋房屋,转移安置21户79人。本文针对其高陡斜坡为缓倾坡内上硬下软型,下卧软层薄,采空区距离陡崖面较远的具体特征,通过geo-slope分析软件,结合现场测绘实际情况,建立地质模型并对其进行数值模拟分析,分析其形成机理。According to the specific characteristics, the high and steep slope is gently inclined, hard in upper lay- er and soft in below layer with a thin underlying stratum inside. The mine-out area is far away from the steep cliff face. In the paper, analysis of the formation mechanism and geo-slope analysis software was used to combine with field mapping the actual situation to establish geological models and numerical simulation.
