Abstract
A review for the numerical methods to simulate natural-slope landslides, serving to discuss and synthesize key findings on this subject, is reported. The past works on the subject can be classified into the two categories such that（1）researches to understand and describe the landslide mechanisms and（2）researches to simulate the process of motion of a landslide mass. A state of the art review corresponding to each category will be demonstrated and it may offer new perspectives on the issue or point out an area in need of further research.
