NUMERICAL SIMULATION OF DEFORMATION AND FAILURE MODE OF KAJIWA LANDSLIDE

It is difficult to get a comprehensive understanding of large soil landslide failure mode by field surveys and other means as conventional drilling. This paper takes Sichuan Liangshan Autonomous Township Kakijiwa landslide for an example. Apply finite difference software FLAC3D combined with the actual landslide geological conditions, geological model, and select weight+storm and hypothetical landslide erosion leading edge for conditional weight+storm two conditions, simulate and study the stability and landslide potential failure modes, expose the maximum stress and displacement during the landslide destroying.
