Abstract: In the ship lock project, the layout of pier structure is an important part of ship lock design, the number and configuration of the pier directly affects the scheduling efficiency and through ability of lock. Taking Changzhou four-lane ship lock project as an example, this paper studies the influence law of the number and layout of pier structure in the approach channel of ship lock and scheduling efficiency and through ability based on operational statistics and mathematical simulations. In this paper, by comparing the effects of increasing the number of piers and the layout of single and double piers on the efficiency and through ability, In addition, a scheduling plan suitable for large multiple-lane lock group is proposed. The study shows that the layout of pier structure should be based on the navigation environment of the locks, with safety as the priority and efficiency as the consideration. A compromised scheme should be adopted for the layout of single side and double side piers for Changzhou four-line locks, that is, the number of right side piers should be appropriately increased, while the left side piers should be kept, so that more ships can berth on the right side or temporarily. The downstream ship entering the approach channel has priority to dock at the right side pier. When the upstream ship is out of the lock, the ship on the left side piers has priority to enter the lock. At this time, the ship on the right side can be moved to the left side piers. This paper provides a reference for the layout of pier structure in the approach channel of ship lock, and also provides a strong basis for engineering design and scheduling management.
