摘要
研究了调压井断面尺寸变化与水电站过渡过程中水锤压力及质量波动的关系,重点探讨了长引水隧洞中调压井的断面尺寸对质量波动周期及波幅衰减速度的影响,并揭示了三者之间的内在关系,所得结论对合理确定调压井断面尺寸有着重要的指导作用。
This paper deals with the effects of variations in surge shaft section sizes upon the problems of water hammer and quality fluctuation existing in transient process of hydropower station. Also,the paper gives the priority on discussing the effects of surge shaft section size in the long water diversion tunnel upon water fluctuation cycles as well as wave attenuation speed and reveals the inner relations among the three. Accordingly, the conclusion obtained will play an important guiding role in the rational determination of surge shaft section sizes.
