摘　　要：抽水蓄能电站水位升降频繁、外部环境多变,长期运行过程中库盆渗控体系的老化问题十分突出。渗漏量是评价抽水蓄能电站库盆运行状态的关键监测指标,将库盆渗漏通道划分为堰型缺陷和深孔型缺陷,确定了水压、温度、时效分量影响因子。通过系统研究库水位、温度、时间对渗漏量的影响,建立了抽水蓄能电站库盆渗漏量统计模型。基于回龙抽水蓄能电站上水库库盆渗漏监测数据,验证了模型的准确性,为回龙电站库盆防渗治理提供了理论依据。Due to the frequent rise and fall of water level and the changeable external environment,the problem of reservoir basin leakage is prominent for pumped storage power station in the process of long-term operation.Leakage is a key index to evaluate the operation state of pumped storage power station basin.In this paper,the leakage channel of the reservoir basin was divided into weir-type defects and hole-type defects,the influence factors of water pressure component were determined.By systematically study the influence of reservoir water level,temperature and time on the leakage,a statistical model of reservoir basin leakage of pumped storage power station was established.Based on the leakage monitoring data of the upper reservoir basin of Nanyang Huilong pumped storage power station,the accuracy of the model was verified.At last,the time when the leakage of Huilong Reservoir basin exceeded the design limit(2,000 m^(3)/d)was predicted,which provided a theoretical basis for the anti-seepage treatment of Huilong Reservoir basin.
