摘　　要：句容抽水蓄能电站地质条件复杂,为分析现拟的渗控措施能否达到预期效果,本文建立了句容抽水蓄能电站三维整体渗流场有限元模型,采用排水孔二次剖分技术和改进的结点虚流量法相结合的方式,实现了对排水孔幕等复杂渗控措施的精细模拟,分析了设计工况下电站的整体渗流特性.结果表明,现拟的渗控措施对库区及地下厂房洞室群渗流场起到了较好的控制作用.The geological condition of Jurong Pumped Storage Power Station is complex. In order to evaluate its seepage control effects, the seepage characteristics under designed condition are analyzed by using an ana- lytical method which contains the secondary subdivision technology of drain holes and the amended node virtu- al flow method; and it simulates the complex seepage control measures such as drainage holes. The results show that the intended seepage control measures are playing a controlling role on seepage field of reservoir re- gion and underground powerhouse.
