摘　　要：延安地区存在独特的双层异质地层结构,即第四系黄土和新近系红粘土组成的二元结构,因而广泛分布饱和塑流状滑坡。介绍饱和塑流状滑坡的基本地质特征,分析其形成的内外因素及运动机理,对延安地区饱和塑流状的滑坡调查和预防具有十分重要的现实意义。Yan＇an has a unique double heterojunction stratum structure ,which is the dual structure of Quaternary loess and Neogene red clay .So saturated and plastic flow loess landslide is widely distributed .We introduce the basic geolog-ical fe6atures of saturated and plastic flow loess landslide ,and analyze the internal and external factors of its formation , and its movement mechanism ,which has very important practical significance for the investigation and prevention of satu-rated and plastic flow loess landslide in Yan ＇an.
