红岩子船闸输水系统优化设计

船闸侧墙廊道闸室明沟消能工布置及消能效果的优劣,直接影响闸室内船舶所受系缆力大小及停泊安全。依托红岩子船闸输水系统水工模型试验研究,探讨筛孔式消能工及通过增加顶盖板优化设计的方案在中高水头分散式输水船闸中的应用效果,通过测定闸室充、泄水水力特性,输水廊道压力及船舶停泊条件等各项指标,发现优化设计方案在船舶停泊条件方面具备更优的性能,同时提出船闸阀门开启方式的运行方案。

Optimum design of filling-emptying system of Hongyanzi ship lock

The layout of energy dissipater and the effect of energy dissipation of lock chamber sidewall corridor ditches directly impact the mooring force and berthing safety of the ship in the lock chamber. Based on the hydraulic model test of the filling-emptying system of Hongyanzi ship lock,we discuss the application effect of the mesh-type energy dissipation and optimum design of adding the energy dissipation cover in the medium and high water head scattered ship lock.By comparing the hydraulic characteristics of ship lock during filling and discharging,the hydraulic pressure of the lock chamber,and mooring conditions of ships,we find that the optimal design of adding the energy dissipation cover has a better performance.An operation scheme of the valve opening mode is also put forward.
