The invention discloses an earthquake landslide risk quantitative evaluation method based on a mechanical model. The method can be used for study of a potential earthquake landslide area near faults.Landslide risk evaluation is carried out through simulated earthquake information, and a landslide risk area is determined, so that disaster protection is carried out in advance, and a site selectionbasis is provided for construction of houses, roads, railways and the like. The method can also be well used for evaluating and analyzing post-earthquake landslide disasters, determining high-risk areas, middle-risk areas, low-risk areas and the like of landslide, and quickly and accurately rescuing disasters.
