三峡库区千将坪滑坡地质力学模型研究

三峡水库初次蓄水不久，千将坪即发生了特大型滑坡。通过对千将坪滑坡滑动区与影响区的勘察试验及对比研究，查明了千将坪滑坡的物质组成、结构及滑坡边界条件，分析了滑坡影响因素及其机制，建立了千将坪滑坡的地质力学模型。分析表明，千将坪滑坡为三峡水库水位上升与降雨联合诱发的水库新生型深层岩质滑坡，水库蓄水起主要和关键作用。

Study on geomechanical model of Qianjiangping landslide, Three Gorges Reservoir

The Qianjiangping landslide, occurred soon after the TGP Reservoir had retained water for the first time, belongs to a large scale landslide. Based on the survey and exploration of the Qianjiangping landslide and its adjacent influenced slope, this paper reveals the components, textures and boundary conditions of the landslide, analyzes the factors causing slide, and sets up the landslide’s geological model and the mechanical model. From the analysis it is indicated that the Qianjiangping landslide was a palingenetic rock landslide trigged by the cooperation of the reservoir water and rainfall; but the reservoir water is a key factor.
