摘　　要：十三陵抽水蓄能电站高水头、大HD值地下埋藏式压力钢管已运行二十多年,且运行环境复杂,充排水风险较大。对2017、2018年压力钢管充排水开展分析,通过复核放空工况相关参数,分析压力钢管运行期和充排水期间的结构应力、外水压力等监测数据,综合评判结果显示压力钢管结构运行状况良好。The buried penstock with high head and large HD in Shisanling pumped storage power sta⁃tion has been in operation for more than twenty years,and the operation environment is complex,with high risk during filling and draining period.The analysis of the penstock filling and draining in 2017 and 2018 was carried out.By reviewing the parameters related to the emptying condition,the monitoring data of structural stress and external water pressure during the operation period and the filling and drain⁃ing period was analyzed.The comprehensive evaluation results showed that the penstock structure was in good operating condition.
