In view of the serious problem of scouring under the sluice gate of the Tidal River, taking the Shanghai area as an example, from the perspective of operation and maintenance management, the scouring mechanism under the sluice and the optimization method of operation and maintenance management were explored. Through the flow state analysis and hydraulic jump formula derivation, the variation law among the water level, the critical water depth of the outer river and Froude number in front of hydraulic jump was revealed. The water level solution formula suitable for the operation and maintenance management of the tidal estuary gate was proposed. The results show that the water level of the outer river fluctuates greatly because the tidal estuary sluice is affected by tidal action; When the water level of the outer river is lower than the critical water depth, it should be prohibited to open the gate; When the Froude number in front of the hydraulic jump section of the outer river level is between 4.5 and 9.0, the drainage of the gate can be effectively exerted, and the erosion under the gate can be effectively reduced. The results can provide a reference for the operation and maintenance management of similar tidal estuarine gates.

针对感潮河口闸闸下冲刷严重的问题,以上海地区为例,从运维管理角度出发,探究闸下冲刷机理及运维管理优化方式。通过流态分析及水跃公式推导,揭示外河水位与临界水深、跃前弗劳德数之间的变化规律,提出适用于感潮河口闸运维管理的水位求解式。结果表明,感潮河口闸受潮汐作用,外河水位变幅较大,当外河水位低于临界水深时,建议关闸;当外河水位推求的跃前断面弗劳德数介于4.5~9.0之间时开闸排水,可有效发挥河口闸排涝功效,且可有效减小闸下冲刷。结果可为类似感潮河口闸运维管理提供参考。

针对感潮河口闸闸下冲刷严重的问题,以上海地区为例,从运维管理角度出发,探究闸下冲刷机理及运维管理优化方式。通过流态分析及水跃公式推导,揭示外河水位与临界水深、跃前弗劳德数之间的变化规律,提出适用于感潮河口闸运维管理的水位求解式。结果表明,感潮河口闸受潮汐作用,外河水位变幅较大,当外河水位低于临界水深时,建议关闸;当外河水位推求的跃前断面弗劳德数介于4.5~9.0之间时开闸排水,可有效发挥河口闸排涝功效,且可有效减小闸下冲刷。结果可为类似感潮河口闸运维管理提供参考。

In view of the serious problem of scouring under the sluice gate of the Tidal River, taking the Shanghai area as an example, from the perspective of operation and maintenance management, the scouring mechanism under the sluice and the optimization method of operation and maintenance management were explored. Through the flow state analysis and hydraulic jump formula derivation, the variation law among the water level, the critical water depth of the outer river and Froude number in front of hydraulic jump was revealed. The water level solution formula suitable for the operation and maintenance management of the tidal estuary gate was proposed. The results show that the water level of the outer river fluctuates greatly because the tidal estuary sluice is affected by tidal action; When the water level of the outer river is lower than the critical water depth, it should be prohibited to open the gate; When the Froude number in front of the hydraulic jump section of the outer river level is between 4.5 and 9.0, the drainage of the gate can be effectively exerted, and the erosion under the gate can be effectively reduced. The results can provide a reference for the operation and maintenance management of similar tidal estuarine gates.
