PRELIMINARY INVESTIGATION ON THE REACTIVATION OF MAOPING LANDSLIDE, GEHEYAN RESERVOIR, QINGJIANG RIVER
清江隔河岩水库茅坪滑坡复活机理初探

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.
