| 摘 要： | 结合小湾水电站高拱坝工程，分析坝区岩体多重理解隙网络渗流的特点及渗流对应力的影响机理，采用多重裂隙网络模型和有限元数值方法对小湾高拱坝建坝蓄水后坝区渗流场和渗流场影响下的应力场进行分析计算。可以看出，建坝蓄水使坝区渗流场发生较大变化，且使大坝附近的坝基岩体竖向有效应力有增大，也使坝肩岩体的拉应力增大。

| Abstract: | This paper analyzes the characteristics of seepage through multiple-level fissure network in rock mass in the area around the dam, and its influence on stress in the light of the Xiaowan high arch dam. Both the multiple-level fissure network model and the finite element numerical method are used to analyze and calculate the stress field under the influence of the seepage field in the dam area after impounding of the Xiaowam reservoir. It can be seen that upon completion of the dam and impounding of the reservoir the seepage field in the dam area changes largely, and the effective vertical stress in the dam foundation rock mass and the tensile stress in the dam abutment rock mass increase. |
