摘　　要：介绍了某水电站运行过程中发现的尾水隧洞砂、石淤积问题,利用近年淤积物清理数据结合机组运行时长、总发电负荷、开停机周期等方面分析机组工况对淤积物存量的影响,并针对性提出运行控制措施,旨在降低尾水隧洞砂、石淤积的不利因素,为电站检修工作顺利开展提供有力保障,为后续安全生产打下坚实基础。This paper introduces the problem of sand and stone deposition in the tailrace tunnel discovered during the operation of a certain hydropower station.It analyzes the influence of unit operating conditions on the deposit stock by using the sediment cleaning data in recent years in combination with the unit operating time,total power generation load,startup and shutdown cycle,and puts forward targeted operation control measures.The aim is to reduce the adverse factors of sand and stone deposition in the tailrace tunnel,provide strong guarantees for the smooth operation of power plant maintenance work,and lay a solid foundation for subsequent safety production.
