摘　　要：传统船闸通过能力的计算基于简单手工排挡得到的主观结果,不能反映船舶随机到闸的动态过程,也未体现出船闸的服务水平。为了全面反映并合理评估船舶随机到闸和船闸运行调度对通过能力的影响,开展船闸通过能力仿真研究。根据航道内船型的比例自动生成船舶随机到达过程,采用最优配比排挡策略和顺序服务排挡策略进行调度,运用两个经典的运筹学模型(二维装箱问题和背包问题)进行过闸船舶的组合和一次过闸总吨位的计算。以此理论为支撑开发了船闸通过能力仿真计算软件,可较好地弥补现有计算方法的不足。The traditional calculation of ship lock capacity is based on the subjective result of simple manual permutation, which cannot reflect the dynamic process of ships arriving at the lock at random, nor does it reflect the service level of the ship lock. To comprehensively reflect and reasonably evaluate the impact of random arrival of ships and operation scheduling of ship lock capacity, this paper carries out a simulation study on the ship lock capacity. The ship random arrival process is automatic generated according to the proportion of ship types in the channel. Scheduling by the optimal matching permutation strategy and sequential service permutation strategy is carried out. Two classical operational research models(two-dimensional packing problem and knapsack problem) are used to calculate the combination of passing ships and the gross tonnage of one-time passing. Based on this theory, a simulation calculation software for the ship lock capacity is developed, which can better make up for the shortcomings of the existing calculation methods.
