Manifold Element Simulation of the Entire Process of Earthquake-induced Landslide Damage and Instability Movement
Landslide disasters induced by strong earthquakes often cause serious damage to the natural environment and social activities.In order to assess the risk of earthquake-induced landslides and reduce the impact of landslide disasters,it is necessary to carry out the seismic dynamic response of rock slopes and the instability movement after damage.process research.The manifold element method that can simulate continuous-discrete problems was used to simulate the dynamic response and movement process of the earthquake-induced Donghekou landslide after instability and damage.The propagation of seismic waves in the slide bed in the rock mass was compared with the dynamic re-sponse and movement of the landslide body.process and accumulation morphology.The results show that compared with the traditional treatment method of treating the slide bed as rigid,by treating the slide bed as an elastic body,the propagation process of seismic waves in the mountain body and the difference in dynamic response of the slope surface can be correctly simulated.The resulting landslide body finally The accumulation shape is more consistent with the actual terrain,and the research results can provide engineering reference for earthquake-induced landslide hazard assessment.
