摘　　要：分析滑坡群形成的地质背景和诱发因素,认为其主要受控于清江河谷地形地貌、地层岩性及地质构造,大气降雨及水库蓄水诱发其发生。分析滑坡群稳定性,认为滑坡群整体处于基本稳定,但在暴雨及库区水位骤降或骤涨的条件下稳定性变差,有局部或次一级滑坡的可能。The analysis of geological background and contributing factors reveals that the landslides are mainly controlled by the valley topography, lithology and geological structure, and caused by rainfall and reservoir impoundment. The analysis of their stability shows that it is stable generally. But it will become unstable with a possibility of landslides locally or at a secondary level in the condition of heavy rainfall or sharp change of reservoir water level.
