摘　　要：洪屏抽水蓄能电站地下厂房地质条件复杂,洞室较多,为检验现有的防渗排水措施的预期渗控效果,利用改进的节点虚流量法求解有自由面的无压渗流问题,采用改进的排水子结构法模拟排水孔,通过计算正常运行工况、降雨入渗、改变排水孔间距等控制性因素,分析了不同条件下地下厂房渗流场的工作状态。结果表明,现有的防渗排水系统合理,可达到预期渗控效果。The geological condition of underground powerhouse of Hongping pumped storage power station is complex and it has many chambers. In order to check the effect of seepage control and drainage, improved nodal virtual flux meth od is used to solve the unconfined seepage problems with free surface. The technique of improved drainage substructure is adopted to simulate drainage holes. The seepage field of powerhouse is analyzed by calculating the normal operation condi- tions, rainfall infiltration and changing the interval of drainage holes. The results show that the existing anti-seepage and drainage system is reasonable, which can achieve the desired effect.
