摘　　要：国外某抽水蓄能电站工程区地下水丰富,地下厂区各洞室位于天然地下水位以下。在电站施工与运行过程中,地下厂房围岩的渗流特性将成为影响工程安全和正常运行的重要因素之一。综合工程地质条件与地下厂房布置特征,建立厂区三维有限元模型,采用稳定渗流分析方法,研究了运行期与施工期地下厂区围岩的渗流场分布特征,并对各洞室的渗漏流量进行了预测,为工程建设提供合理建议。The underground powerhouse for a pumped storage power plant lies below the natural groundwater line.During construction and normal operation period,the seepage behavior in the surrounding rocks of underground caverns is one of the most important factors which may affect the safety and operation of the hydropower station.Based on the geological investigation results and the layout of the project,a three-dimensional finite element model was generated.The steady-state seepage model was adopted to analyze the distribution characteristics of the seepage field.Based on these,the amount of seepage from the caverns was predicted to provide reasonable suggestions for construction.
