Making the ship waves by the speedboat rapid sailing in the downstream approach channel,we study the influence of ship waves on the operation characteristics of Jinghong ship lift.The experimental results show that ship waves of the downstream approach channel has no obvious effects on the water surface fluctuations of the ship chamber pool.When the ship chamber and downstream approach channel docking standby,ship waves will affect the water surface fluctuations of ship chamber and threaten the safe berthing of the experimental ship in the ship chamber.To ensure the safe berthing of ships in the ship chamber when Jinghong ship lift’s ship chamber has ship berthing inside and downstream approach channel docking standby,the sailing speed of ship in the downstream channel should be strictly controlled.
