Abstract
The post-quake rainfall frequently induces large-scale landslides, which result in the loss of lives and economic damage. The observation of past slopeland disasters in Taiwan shows that the frequency of landslide occurrence increases remarkably after massive earthquakes. However, the understanding of correlation between seismic activity and post-quake slope stability is limited. As a result, the research on the influence of earthquake intensity on post-quake slope stability is vital for slopeland disaster prevention. This study is utilizing the self-developed hydrological environment testing box for slope model tests on the geotechnical centrifuge and shaking table. Through the static and dynamic modeling tests, the variations of landslide scales and rainfall intensities to trigger slope failures are investigated to understand the slope failure behavior due to post-quake rainfall.
