摘　　要：武山县自然环境条件整体属地质灾害易发区,当遇到强降雨时,极易引发滑坡、泥石流等地质灾害。杜庄村H1滑坡因暴雨局部复活,并牵引多处次级滑动变形。根据滑坡物质组成及结构特征分析,认为该区域滑坡形成与区内地形条件、水文地质条件、地层岩性、地震作用和人类工程活动等因素关系密切,其中以地形、水文条件为主。针对杜庄村滑坡变形特征和成因机制,以局部坡体地下水疏干排水工程和沟道反压拦挡工程为主,辅以地表截排水措施和监测预警措施进行治理。The natural environment conditions of Wushan County as a whole is a geological disaster prone area,when encountering heavy rainfall,it is very easy to cause geological disasters such as landslide and debris flow.The H1 landslide in Duzhuang Village was partially resurrected due to heavy rainfall,and hauled multiple secondary sliding deformations.Based on the analysis of the material composition and structural characteristics of the landslide,it is believed that the formation of the landslide in this area is closely related to the topographic conditions,hydrogeological conditions,stratigraphic lithology,earthquake action,and human engineering activities in the area.of which the topographic and hydrogeological conditions are mainly factors.For the deformation characteristics and cause mechanism of Duzhuang Village landslide,the local slope groundwater drainage engineering and ditch counterpressure barrier engineering are used as the main measures,with surface drainage measures and monitoring and warning measures as auxiliary measures.
