In the construction of highway and railway in mountainous areas in China, the slopes with poor stability are often produced, which causes the deformation and failure cases frequently. Take the subject of a large-scale landslide in bedding rock in Guiyang to Xinzhai highway construction, by the field exploration and the investigation on the external factors of unfavorable geological environment and human being activities, the simulation is made on the characteristics of tractive landslide activity and the analysis is made on the causes of the landslide. According to the characteristics of tractive landslide, the corresponding control measures are put forward.
