摘　　要：通过对贵州盘县某移民安置点滑坡及其影响范围进行调查和研究分析,认为研究区滑坡为顺层牵引式土质滑坡,滑坡的产生主要应受地形地貌、岩土性质、大气降水等因素及其相互作用的控制,其中大气降水和地下水的共同作用是诱发滑坡发生的主要原因,"水楔"推力是滑坡下滑的关键因素。The landslip and the impact area of the resettlement arrangement spot in Panxian,Guizhou Province was researched and analyzed. The results show that the landslide is the bedding layer-traction type soil landslide which should be mainly controlled by topography,geotechnical properties,atmospheric precipitation and other factors. The interaction of atmospheric and groundwater of which,are the main factors for induced landslide,and the ＂ water wedge＂ force is a key factor of landslide.

关 键 词：滑坡 “水楔”作用 边坡稳定性 影响范围
