摘要
针对李家峡水电站Ⅱ＃滑坡体的工程地质特性与物理力学性质，根据其宏观稳定性态反演推算出滑面的ｃ，φ值；采用非线性弹性、弹塑性介质力学模型模拟水位变化时的渗透动水压力作用，对该滑坡体的滑动性态、滑速、涌浪作了系统的三维有限元分析与评价，为该工程的安全合理拉闸蓄水提供了科学依据。
Based on the geological condition and mechanical property of Ⅱ # slope in Lijiaxia power station, the c, φ values of the slipping surface are back determined with the macro stability of the slope. The effect of dynamic seepage pressure is simulated with nonlinear elastic and elasto plastic model. The slipping behavior, slipping velocity, and water wave are evaluated with 3 D FEM. This can be provided as a scientific basement for the safety and efficiency of the project.
