摘　　要：文章介绍了洪屏抽水蓄能电站地下厂房渗流场研究的方式和方法,阐述了地下厂房防渗排水设计方案的确定过程,总结了地下厂房防渗排水设计的基本思路,得出:地下厂房排水系统设计时,利用示踪试验分析渗流场的分布,对探洞渗水量反演分析,来确定地下厂房渗水量是必要和适宜的;对探洞应尽量做到临时和永久使用相结合;渗漏和检修排水具备自流排水条件的,应首先考虑自排。The paper introduces study method of seepage field for underground powerhouse of Hongping pumped storage power station,describes the determination process of anti-seepage drainage design plan of the underground powerhouse and summarizes the basic thought of the anti-seepage design of the underground powerhouse.The result shows that it is necessary and appropriate to find the seepage through the analysis of the seepage field layout by tracing experiment and the inversion analysis of testing tunnel seepage;the testing tunnel should be used temporarily and permanently;self-drainage should be first considered if leakage and maintenance drainage have the self-drainage function.
