摘　　要：结合工程实践 ,应用斜坡稳定性常规分析方法 ,在充分分析稳定性各影响因子的基础上建立稳定性分析反演模型 ,采用试验与参数反演的方法确定万州和平广场滑坡区斜坡稳定性定量分析的物理力学参数 ,并且应用于计算分析。分析结果表明 :在各种工况下 ,滑坡区堆积体除局部地段外均处于稳定状态 ,仅在库水位由175m骤降至 14 5m(吴淞高程 )时 ,各工况对应的稳定系数降低 ,其中 15In combination of engineering practice and adopting conventional analysis method of slope stability, the reversion model for the stability analysis is set up on the basis of full analysis on various influencing factors. The physical and mechanical parameters for quantitative analysis on the slope stability of Heping square landslide of Wanxian city were determined through test and reversion calculation and applied in computation and analysis. The analysis results demonstrate that except for a local area, the piled up mass of landslide area is in stable state under various operation condition of the TGP reservoir and only under the condition of water level drawdown from 178 m to 145 m, the stability coefficients corresponding to various operation conditions decrease, of which the area near 15-15′ profile is in unstable state.
