Characteristics analysis of granular landslide using shaking table model test

A small-scale shaking table model test was used to investigate the characteristics of the granular landslide deposits under influences of seismic wave. The model was subjected to horizontal and vertical seismic waves. The maximum displacement, width, thickness and area are measured. The results show that vibration frequency significantly influences the deposit shape. The maximum displacement, width, thickness and area of the deposit increase with the enhanced frequency when the vibration orientation is horizontal. The maximum displacement of granule is relatively smaller when the vibration orientation is vertical, while the deposit width and thickness turn out to be greater. Other characteristics of landslide deposits under different seismic waves and some preliminary guidelines for design of engineering protective structures are also provided in this study.
