摘要
基于饱和—非饱和渗流理论,采用有限元法对降雨条件下边坡各向异性渗流场动态变化进行了数值模拟,分析了降雨过程中边坡地下孔隙水压力分布、浸润线位置变化规律。研究结果为边坡的稳定性分析和滑坡预测提供了重要的分析依据。
Based on saturated-unsaturated seepage theory, numerical simulation of ground water seepage in a anisotropic permeablity slope under persistent rainfall condition was studied by use of finite element method. The change law of pore water pressure and free water elevation is gained. The study can provide important basis for slope stability analysis and landslide prediction.
