Summary:Starting from the basic equation of landslide movement, a numerical model for landslide movement was presented through the calculus transformation of differential equations and further numerical discretization. Also, some typical analytical examples and real landslides were calculated and analyzed by applying the established numerical model. The results show that the numerical results are in good agreement with the analytical solutions and the actual disasters; therefore, they verify the correctness and effectiveness of the presented numerical models. Compared with existing landslide movement models, the established model has some special characteristics, such as static-dynamic unity, clear physical conception, and simple numerical format, which facilitate the analysis and provide references for disaster forecast.
