Abstract

Trampoline effect is introduced to interpret the mechanism of long run-out movement of earthquake-induced landslide in Multiplex Acceleration Model (MAM). In previous study, this model was verified by a shaking table test. However, there is a scale limitation of shaking table test to investigate MAM in detail. Thus, numerical simulation was carried out in this study to validate MAM with respect to field phenomenon in Wenchuan Earthquake (Ms. 8.0). A truck threw upwards by seismic force was discussed based on the simulation results. The results indicate that trampoline effect could be composed by continuous collisions in P-Phases of earthquake and makes the intensity grow up. The results show that MAM is acceptable and applicable.
