Abstract: In view of landslide status of Shengli open-cut,the paper analyzed internal factors of landslide formation of open-cut,namely topography and geomorphology,formation lithology,geological structure and soft layer,expounded inducing factors of landslide distribution of open-cut,namely rainfall,earthquake and artificial action,and destructive action to slope of open-cut made by soilfrost.It drew conclusion that distribution and development of landslide is controlled by topography,formation lithology and geological structure rigorously and is induced by soft layer and rainfall mainly,which provides basis research for further analyzing and evaluating landslide phenomenon of Shengli open-cut.
