摘　　要：充排水试验是抽水蓄能电站输水系统正式运行前的第一次受荷试验,通过原型监测资料分析可掌握结构性态变化,了解缺陷部位,以便及时消除安全隐患,保障电站安全运行。根据某抽水蓄能电站原型监测资料,研究了充排水试验中输水系统围岩变形、支护应力、渗透压力等监测项目的变化规律,分析结构性态变化,并与国内其他工程监测成果进行对比分析。研究表明:充排水试验期间,(1)引水系统整体性态正常。工程对比来看,由于该电站所处地质条件较差,其充排水试验期间围岩变形、接缝变形、支护应力变化均较其他工程明显。Charge and drainage test is the first load test before the formal operation of diversion system in Pumped Storage Power Station. Through prototype monitoring data analysis, the structural behaviorandthe defect location can be charged. It is also important to eliminate security risks, andto ensure the safe operation. According to monitoring data of Liyang Pumped Storage Power Station,thedeformation surrounding rock,supporting stress, osmotic pressure and other monitoringresults are researched, the behavior of structural areanalyzed,and monitoring results are compared with other domestic engineering. The study shows that during charge and drainage test, Liyang water diversion system is under normal state. In comparison with the other projects, due to the poor geological condition of Liyang power station, the deformation of surrounding rock, the deformation of joint and the change of supporting stress are more obviousduring the period of charge and drainage.
