Abstract: The current situation and existing problems of the cargo handling capacity of the Three Gorges ship lock were analyzed. According to the arrival quantity of ship and the capacity of ship passing through the lock at one time considering the weight, the simulation model of ship type passing through the lock was established with Anylogic software, and the maximum cargo handling capacity of the Three Gorges ship lock was calculated. The results show that the influence factors of the cargo handling capacity of the Three Gorges ship lock are mainly concentrated in three aspects such as ship lock, ship and ship lock operation organization, which specifically means the type of cargo ship passing the lock, the actual load rate of cargo ship passing the lock, the operation and management mode of the lock and the tonnage limit threshold of ship passing the lock. The proposed simulation model predicts that the maximum cargo handling capacity of the Three Gorges ship lock is 179 million tons.

摘要： 分析了三峡船闸过货能力现状及存在问题；根据设置的船舶到达量与考虑权重情况下一次过闸船舶容量，用Anylogic软件建立了分船型过闸的仿真模型，计算了三峡船闸的最大过货能力。结果表明：影响三峡船闸过货能力的因素主要集中在船闸、船舶、船闸运行组织3个方面，具体有过闸货船船型、过闸货船实载率、船闸运营管理模式、过闸船舶吨位限制门槛等；仿真模型预测三峡船闸的极限过货能力为1.79亿吨。
