    Abstract

  • The Yarlung Zangbo River Grand Canyon area in Tibet is a highly prone area for earthquake-triggered landslides,where several landslides have occurred before. Taking the Yigong Landslide as an example,this article analyzes the frequency response characteristics of the Yigong Mountain by using the FLAC3D finite difference method. Based on the results,the amplification effect of the Yigong Mountain under seismic waves is discussed and the stability of the Yigong Landslide remnant under the condition of near-field strong earthquakes is predicted. Results show that the overall predominant frequency of the Yigong Mountain is at a low value. The predominant frequencies of the mountain top mainly concentrate below 1 Hz,while that of both sides of the mountain top vary from 2~6 Hz. Under the action of seismic waves,the predominant frequencies of the top and both sides of the mountain appear different degrees of amplification,and that in the mountain interior along the height upward shows the change of first increasing then decreasing,and then increasing again. The calculated results are basically identical with the frequency analysis. Stability analysis shows that the Yigong Landslide remnant keeps stable with a safety factor of 1.27 in static condition; however,the results under the earthquake show the occurrence of instability and failure. Finally,it is predicted that the damage of the Yigong Landslide remnant will obviously increase when considering both horizontal and vertical seismic waves. Therefore,it is necessary to strengthen the risk analysis and prediction of mountains under the condition of near-field strong earthquakes.
