摘　　要：基于对茅坪滑坡体1993～2000年的降雨、水库水位、变形等监测资料的综合分析,初步认为茅坪滑坡体复活是其东侧白岩危岩体中不合理的采煤活动引起的。采煤活动诱发的危岩体开裂和崩塌,加强了滑坡体与危岩体的水力联系,间接扩大了滑坡体的受雨面积。因此,从滑坡体变形的影响因素上讲,降雨(特别是强降雨)的影响较大,水库蓄水和库水位波动的影响范围主要集中在滑坡体前缘。Based upon the analysis of monitored data, such as precipitation, reservoir level fluctuation and deformation, etc. from 1993 to 2000, preliminary conclusion is reached that the reactivation of Maoping landslide is caused by the irrational coal mining in the Baiyan cliff to the east of the landslide. Coal mining-induced cliff rock cracking and collapse enhanced hydraulic connection between the landslide and the cliff, indirectly increased the precipitation area of the landslide. So the landslide deformation is greatly influenced by precipitation, especially intensive precipitation. Reservoir impounding and water level fluctuation mainly influence the deformation of the toe area.
