[CS14-06] Basic study on run-out and accumulation of soil caused by landslide by using MPM
Keywords:landslide, soil, material point method, accumulation behavior
In recent years, the slope collapse occurred by large earthquake caused serious structure damages. Direct evaluation of the influence caused by landslide is seemed to be necessary for the significant infrastructure. The author carries out reproduction analysis of run-out, accumulation and impact behavior obtained by the experiments. Material Point Method was used. It is thought that the behavior of not on run-out but also accumulation vary according to the characteristic of the slope shapes. Here, the influence that the difference in factor of the slope collapse such as slope shapes affected to accumulation behavior is carried out by using MPM where reproducibility was confirmed.
