Abstract

The practical techniques for risk analysis of earthquake-induced landslide are presented and discussed. The procedure of frequency analysis and consequence analysis for earthquake-induced landslide is proposed. A new concept of "critical line" proposed for the first time can make Monte Carlo simulation easier and more effective. The key problem in consequence analysis is how to estimate the travel distance, velocity and volume distribution of landslide, which can be solved by using the discontinuous deformation analysis (DDA) simulation. The results from a practical DDA simulation show the agreement with those observed from the past landslides. Therefore, the proposed way for risk analysis of earthquake-induced landslide will be put into practical use.
