摘　　要：木竹坪滑坡发生于2007年5月10日,总方量约800×104m3,是水布垭库岸的重大滑坡灾害之一。根据实地调查资料,阐述了滑坡区基本地质条件及滑坡基本地质地貌特征。结合滑坡稳定性计算分析了滑坡的成因机制,认为木竹坪滑坡的发生是内外因共同作用的结果,初步推断认为属于牵引型滑坡。Muzhuping landslide, 700 million m3 in volume, which occurred in the Shuibuya Reservoir area on May 10, 2007, is one of the serious landslide disasters in this area after second stage impounding. And Iit caused a serious loss of the property. According to the on-the-spot survey on this landslide, the paper introduces the geological background in landslide area and the geologic and geomorphic characteristics. Synthesizing the landslide stability calculation, it is considered that the occurrence of Muzhuping landslide is the union result of inner and outer cause.
