By adding an annular hydraulic device between the ship-berthing pipe and batter pile,and partially separating the batter pile and major structure,a new type of floating ship-berthing system was proposed.The bearing capacities of ship-berthing pile and batter pile were also analyzed under the impact and load of ship by combing with the numerical simulation.Comparing with the existing high-pile wharf and floating ship-berthing system,this system has the advantages such as being convenient to use,protecting the pier body from being impacted,slowing down the descent rate dock carrying ability,etc.From the considerations of safety use and shipping economy,the new type of ship-berthing system is better in structure and safer in use,and can improve the wharf handling efficiency and has a broad application prospect.
