摘　　要：十三陵抽水蓄能电站高水头、大PD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。本文对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结构应力和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 high head and underground buried penstock with large PD value of Shisanling Pumped Storage Power Station has been operating for more than twenty years.And the operating environment is complex.The risk of filling and drainage is large.The filling and drainage analysis of penstock for 2017 and 2018 is carried out in this paper.The relevant parameters are reviewed of the emptying condition.Structural stress and external water pressure of penstock are analyzed in operation period and filling and drainage period.The comprehensive evaluation results show that the structure of penstock runs well.
