Huzhou ship lock has a large plane size,large instantaneous flow,high water delivery intensity,no energy dissipation workers in the lock chamber,berth conditions in the lock chamber to be tested,and asymmetric layout of the approach channel,which is prone to reflux,oblique flow and other hydraulic problems.Through the hydraulic physical model test with a scale of 1:30,the hydraulic characteristics of the water conveyance process of the lock,the pressure characteristics of the water conveyance gallery,the berth conditions of the ship,the flow conditions of the inlet and outlet and the approach channel are studied.The research results show that the berthing conditions in the lock chamber and the navigable flow conditions in the downstream approach channel are obviously improved after adding the sill and optimizing its layout.Under the recommended valve operation mode,all the hydraulic indexes meet the specifications and design requirements.The research results can provide reference for similar projects.
