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.
