Abstract Based on geological exploratory profile of 1# landslide in Shangsan highway，numerical analysis model is established. The characteristic of deformation and failure of slope under accumulation loading is studied by using contact model of elastic-plastic material. The mechanical mechanism of occurrence and development of deformation and failure of slope is revealed. The research results show that accumulation loading on slope of loose accumulation mass directly changes slope stability and seepage condition of groundwater，and reduces stability of slope mass，which finally leads to occurrence of landslide.

Key words： rock and soil mechanics accumulation loading of highway contact finite element stability analysis
