Abstract

Abstract

A large number of ancient landslides with double or multi sliding zones exist in the Three Gorge Reservoir (TGR) area. However, there are few studies on the deformation characteristics and stability changes characteristics of the reservoir landslide with double sliding zones under the action of reservoir water level (RWL) fluctuation. In this paper, the deformation characteristics of Taping landslide were obtained by filed investigation and the in-situ monitoring data. Furthermore, numerical simulation was carried out to investigate seepage filed and stability characteristics of the Taping landslide under RWL fluctuation and precipitation. Then the responses of the two different sliding zones in the Taping landslide to RWL fluctuation and precipitation were revealed. The result indicates that the Taping landslide shows a significant retrogressive failure pattern. Precipitation mainly has a greater influence on the shallow sliding zone, and the influence of precipitation on the deep sliding zone is low. As the RWL rises, the stability of the shallow sliding zone decreases and the stability of the deep sliding zone increases. As the RWL drops, the stability of the shallow sliding zone increases and the stability of the deep sliding zone decreases.
