• MECHANISM OF HIGH SPEED & LONG-DISTANCE MOVEMENT OF THE DEBRIS FROM LANDSLIDE INDUCED BY EARTHQUAKE

抄録

It is very important to understand the mechanism of high speed & long-distance movement of the debris from earthquake induced landslides so as to estimate the real dangerous area. In this study, at first, a new model called Multiplex Acceleration Model (MAM) is proposed for understanding the mechanism of high speed & long distance movement of the debris. And then, model shaking table tests and numerical simulation are carried out to verify the proposed model. The MAM has been verified successfully by both laboratory model test and DEM numerical simulation. Up to 3.4 times of movement distance is observed for the earthquake with 400Gal of acceleration comparing the case without earthquake. The movement distances are different from shape to shape because the earthquake vibration causes the rotation or flying motion easily contrary to the sliding motion in the case without earthquake.
