摘　　要：船闸阀门开启时间对闸室通航效率、输水廊道压力和闸室停泊条件等产生影响,针对阀门运行方式优化问题,采用物理模型试验对船闸进水口水位、阀门段输水廊道压力特性、闸室和下引航道内船舶系缆力等水力特性进行分析,结果表明:闸室和下引航道内前横、后横和纵向3个方向的船舶系缆力均随阀门开启时间增大而减小,且纵向船舶系缆力大于横向船舶系缆力。随着阀门开启时间增加,充水时阀门段输水廊道压力先减小后增大,泄水时则逐渐增大。综合考虑当阀门开启时间为6 min时船闸整体运行效果较好,该成果可为实际船闸运行提供技术支撑。The opening time of ship lock valves has an impact on the navigation efficiency of the lock chamber,the pressure of the water conveyance gallery,and the berthing conditions of the lock chamber.To optimize the operation mode of the valves,physical model tests are used to analyze the factors such as the water level of the ship lock inlet,the pressure characteristics of the water passage,the ship mooring force in the lock chamber and the downstream channel.The results show that the mooring force of ship in front transverse,rear transverse and longitudinal direction decreases with the increase of valve opening time,and the mooring force of ship in longitudinal direction is greater than that of ship in transverse direction.With the increase of the opening time of the valve,the pressure in the passage gallery decreases first and then increases during water filling,while gradually increases during water discharge.It is considered that the overall operation effect of the ship lock is better when the valve opening time is 6 min.The conclusion can provide technical support for engineering practice.
