摘　　要： 以某抽水蓄能电站地下厂房为例,探讨了渗控措施对地下厂房洞室围岩渗流特性的影响。依据裂隙岩体等效-离散耦合模型,结合固定网格虚流量法和排水子结构法,建立了大型地下洞室群的渗流有限元模型;对采用防渗帷幕和排水孔幕等渗控措施的地下洞室群围岩,在不同工作条件下的渗流进行了分析。计算结果表明:渗控措施对洞室群围岩的渗流起到了良好的控制作用。计算结果可为类似工程设计提供理论依据和指导。 Taking a pumped storage power station plant for example, the influence of seepage control measures on the surrounding rocks＇ seepage characteristics of underground cavern is explored here. Based on the fractured rock mass equivalent-discrete coupling model, and combined with the fixed grid virtual flow law and drainage substructure method, a large underground cavern group＇ s seepage finite element model is established. Then the analyses of the seepage characteristics of underground cavern group＇ s surrounding rock are conducted under different working conditions. The results show that the seepage control measures have a good role in the control of seepage. The results could provide theoretical basis and guidance for the similar engineering design.
