Abstract

Landslide movement is a phenomenon that a relative shear movement on the slip surface between moving layer and immobile layer continues. It is effective to apply a particular numerical analysis method that the reproduction of continuous relative displacement (large displacement) on the slip surface can be simulated stably. In this study, we examined the applicability of the finite difference method formulated by the explicit dynamic formulation to the landslide movement analysis. This numerical analysis method is applied when slope collapse or reactivated landslide is induced. This method allowed us to reproduce characteristic phenomenon respectively observed in such slope disaster.
