摘　　要：贾沙滑坡处于蠕变阶段,变形范围大,属大型牵引式滑坡。滑坡体为第四系粉砂夹粘土层。滑坡成因主要由水的作用引起的,滑坡体上部地层土层结构松散,土质亲水性强,且土体处在山的斜坡上,在饱水之后形成下滑。同时,人为因素也是引起贾沙滑坡产生的主要因素之一。贾沙滑坡形成原因的研究对滑坡防护与治理有重要的意义。同时可保证贾沙街居民的生命和财产安全。Jiasha landslide is a large scale tractive landslide and on the stage of creeping deformation. Landsilde body consist of siltstone and mudstone of . The landside deformation is the result of the geological condition, precipitation and human activities. precipitation is the most important factor for forming Landslide, which is of layer-structure. Hhuman activities are also one of reason for Jiasha landslide development. These factors are very important for preventing and controlling with the landslide.
