Research Abstract |
During the 2008 Sichuan earthquake(M8. 0), more than 800 landslide dams formed. To clarify the formation and failure of these landslide dams, we conducted detailed field survey and monitoring on some big landslide dams. The geological, geomorphological and movement features of the original landslides were investigated and the geotechnical properties of the dam sites were surveyed. We also surveyed some landslide dams triggered by earthquake and/or rainfall in Japan. Based on these results, we proposed a new approach for evaluating the collapse failure risk of landslide dam due to overtopping.
