摘　　要：闸墙长廊道侧支孔输水系统属简单类分散输水形式,采用该形式的船闸在输水过程中侧支孔涌入的水流在闸室内不易均匀分布,常出现闸室内水体剧烈紊动的现象,影响船只的停泊条件,因此常需在闸室内增设消能设施。通过数值模拟的手段研究船闸输水过程中的消力槛的消能机理及消能效果,研究结果表明:布设消力槛可以有效地降低射流进入闸室后的流速,改善闸室内水流流态,具有良好的消能效果。Long-culvert filling and emptying system of ship lock is a sort of simple longitudinal filling and emptying system.And the flow from lateral holes is not evenly distributed in lock chambers during the filling process,which will exert a force on the ship,causing the deterioration of berthing conditions.Therefore,energy dissipaters are needed extensively.This paper,based on the numerical simulation methods,carries out a research on the baffle sill's energy dissipated mechanism and effect.The results show that setting the baffle sill could effectively reduce the flow velocity and improve the flow pattern in the lock chamber,which plays a good role in energy dissipation.
