摘要：Landslide disaster is a kind of main geological disasters. Countries in the world are all harmed by landslide disaster seriously. Achieving landslide�s 3D dynamic simulation is helpful for the relevant regulatory authorities to guide the Prevention and Treatment of landslide disasters. For simulating landslide more intuitive and more realistic, and predicting the loss situation, we achieved landslide�s 3D dynamic simulation based on landslide information extraction, modeling, finite element subdivision, and applying motion-displacement equation. At the same time, we take landslide disaster effect factors into consideration as the parameters variable of motion-displacement equation. The effect factors include lithology, soil moisture, vegetation coverage, acceleration of gravity and terrain and so on. At last, the simulation result would be taken as a guide to provide reference in landslide disaster relief. As a result, we can realize the dynamic simulation of landslide process, calculate area influenced by landslide, by calculate landslide�s motion trajectory. On basis of it we can reduce loss amount of our economy caused by the landslide also.
