Numerical simulation study on earthquake-induced landslide stability evaluation

Landslide is one of the most dangerous geological hazards in the world, and its stability is affected by many factors. Especially in the earthquake-prone area, the earthquake plays a quite significant role in the stability evaluation of landslide. A typical landslide in Western China area was taken as an example, from which the geological model of landslide with considering the earthquake effect was established. The dynamic analysis module of finite difference software FLAC3D was carried out the numerical simulation in order to evaluate the stability of the landslide under the condition of earthquake effect. The result indicates that the numerical simulation analysis is in concordance with the engineering practice of the landslide. This study can provided a significant scientific basis for the stability evaluation of landslide in earthquake-prone area of Western China.
