Abstract: Soil-rock mixture landslide is a representational geological disaster of landslide. This landslide is broadly distributed in nature, and it is more complex than other landslides, it often brings huge calamity to human. Zhoujiawan landslide which is located on the north bank of Yangtze River, Country Badong, Hubei Province, China, belongs to this type of landslide, It is a very important part of the Huanglashi ancient landslide group. The obvious deformation of the landslide began in the middle age of 1980s, and at that time the deformation of the landslide induced many cracks on the ground. Now the deformation of the landslide is pricking up, and it is on the creep stage. The existence of Zhoujiawan landslide is a potential threat because there is a Shiliushubao landslide at the front of Zhoujiawan landslide. The special factors like geological surrounding, shape, structure and evolvement of the landslide are analyzed by means of geological analysis and engineering geomechanics. The three-dimesional geological model is also established. The stability of the landslide and the failure mechanism are studied through the numerical simulation technique

Key words: soil-rock mixture landslide(S-RML), stability analysis, strength reduction method, spatial effect
