Mechanisms and Modeling of the Catastrophic Landslide Dam at Jure Village, Nepal
This study clarifies the failure mechanisms of the 2014 catastrophic large deep-seated landslide and simulates the dam formation process at Jure Village, Nepal, through site investigations, ring shear tests, and LS-RAPID computer simulation model. The detailed analyses suggest that the Jure landslide triggered by a high cumulative rainfall slid along bedding-plane faults of weathered phyllite and schist on the slope of an ancient landslide terrain. The landslide comprised two separate subblocks; the upper and lower slopes, whose sliding mechanisms differed from each other. The test results indicate that the upper subblock of the landslide was triggered by rainfall with a critical pore pressure ratio of . The lower slope failure resulted from a dynamic loading process initiated by the downward movement of the upper slope. In the LS-RAPID model, the evolution process of landslide damming the river was reproduced and verified based on the observed geomorphic evidence and recorded data. The study shows landslide mobility acted as the critical factor leading to the landslide dam formation, in addition to the geomorphic indexes.
