Abstract
The 5.12 Wenchuan earthquake had induced thousands of large-scale landslides. Through the field investigations and surveys on deformation and destroy characteristics of 20 landslides induced by the Wenchuan earthquake, and combined with the shaking table test and numerical simulation, we found that the deformation and mechanical mechanism of these large-scale landslides are different from those landsides induced by routine gravity. On the condition of strong shock, the most essential deformation and destroy element of the slope rock mass are tension-cracks and shearing slide, and mainly based on tension-cracks. According to the geological and topographical change, the large-scale landslides induced by the Wenchuan earthquake can be classified into five genetic types, i.e. tension-strike slip, crack-bedding slip, tension-horizontal slip, tension-scattering slip, and tension-shearing slip.
