摘　　要：采用岩体渗流场与应力场耦合分析的多重裂隙网络模型 ,对小湾水电站坝区建坝蓄水后的渗流场与应力场进行了三维有限元分析与计算。计算结果可知 ,建坝蓄水使坝区渗流场的补给关系发生变化 ,且使大坝附近的坝基岩体竖向有效应力增大 。Analysis of coupled seepage and stress fields in the area around the dam of Xiaowan hydropower station is executed by means of the model of multi level fracture network for coupled seepage and stress fields in rock mass and the finite element method. It can be!shown from the computation results that storage of the reservoir makes the seepage field change, and makes the effective vertical stress in rock foundation near the dam and the tensile stress in the abutment rock mass increase.
