Abstract: A systematic classification system has been established in the slope engineering, and corresponding standards and literatures have been published. However, the existing slope classification is focused on the slope stability analysis and the reinforcement methods. There is no classification system based on the landslide early-warning system. Different slope deformation evolution processes will directly affect the methods and results of landslide warning. It is of great significance to establish slope classification methods based on the deformation evolution processes and to establish slope classification system focusing on the landslide early-warning. Through the investigation and the analysis, it is pointed out that the deformation evolution process of the slope failure is different, and the induced factors and failure modes are the main factors affecting the deformation evolution process of the slope failure. The deformation evolution characteristics of the rainfall-induced landslide, the earthquake-induced landslide, the artificially induced landslide and the reservoir water-induced landslide were summarized. On this basis, a slope classification method based on the deformation evolution process is proposed. A slope classification system focusing on the landslide warning can be established by using the proposed classification method. The research results can be used as a reference for the slope stability research and the landslide prediction and the warning system.
