Abstract

Due to the intensive rainfalls in October 2008 and the heavy snowfalls in February 2009, the Zhenggang deposit exhibited a high probability of landslide reactivation. A good understanding in landslide run-out prediction and failure mechanism analysis was thus highly urgent. In this study, the landslide dynamic simulations were performed for studying the run-out prediction and the failure mechanism of the Zhenggang deposit. The impacts of the friction coefficient at sliding surface and the contact damping ratio on landslide run-out were investigated. The potential improvement of the proposed landslide run-out modeling was discussed.
