摘要
三峡船闸六闸首阀门设计工作水头为22.6 m。在建立三峡上下游水位与六闸首阀门工作水头关系模型基础上,对三峡枢纽调峰对六闸首阀门工作水头的影响进行了分析研究,发现三峡电站调峰下游水位日变幅3 m,在某些上下游水位组合条件下,调峰过程中六闸首阀门的工作水头可能会超过设计水头,建议深入研究其影响程度及相应的对策。
The working head of first valve in Three Gorges＇s six gates is designed as 22.6 meters.As the amplitude of water level in downstream will reach 3 meters when Three Gorges Power Station adjusts the water level,in some cases of combination of upstream level and downstream level,the working head of the first valve in six gates will exceed the design head.A working head relationship model of upstream and downstream water level of Three Gorges and six gates＇ first valve is established.Moreover,the effect of peaking on the working head of the first valve in sixth gates is analyzed.Further research and countermeasures are suggested.
