摘要
从库水位和降雨二者共同作用的角度,分析了三峡库区胡家坡滑坡的稳定性特征,并给出了后续库水位变化过程中边坡变形破坏的预测。该模型基于比二维更能反映真实情况的三维有限元计算,采用Mohr-Columb和拉破坏准则相结合的复合准则,并对滑坡的库水位和降雨耦合的边界特征进行了分析,最后通过对极端工况模拟结果的分析,得出了一些有意义的结论。
The stability of Hujiapo landslide in the Three Gorges Reservation Area was performed by considering the pool level fluctuation and the precipitations.The progressive deformation of the slope induce by the pool level fluctuation was predicted.The landslide was simulated with three dimensional finite element analysis using Mohr-Coulomb constitutive model and tension failure criterion under the pool water level fluctuations and precipitation conditions.The extreme loading conditions were simulated in the numerical analysis.
