洪屏抽水蓄能电站地下厂房排水系统设计探索

Design Exploration of Underground Powerhouse Drainage System in Hongping Pumped-storage Power Station

洪屏抽水蓄能电站地下厂房水文地质条件复杂,地下水活动强烈。在设计阶段,对地下厂房进行了地下水示踪试验,并对地下厂房渗水量进行了解析法与数值法的对比分析,为地下厂房排水系统设计提供了依据,最终确定排水系统为5层排水廊道为主,经实践结果表明,该排水系统设计方案合理有效。

The hydrogeologic condition of underground powerhouse in Hongping Pumped-storage Power Station is very complex and the activity of underground water is strong. The design scheme of underground powerhouse drainage system is confirmed according to the tracer experiment and the analytical and numerical leakage prediction results of underground water. The drainage system consists of five layers of drainage gallery and corresponding drainage curtain. The practice has proved that the design of drainage system is successful.
