摘　　要：目前长洲水利枢纽共有4线船闸,2021年下行量达1.19亿t,船闸运行接近饱和。为研究新建船闸建设方案,需结合过闸运量预测,分析既有船闸和新建船闸的通过能力。根据过闸船舶统计数据和发展变化的规律,预测2030年过闸船舶的组成、各吨级船舶的平均载重吨和装载系数。采用离散事件系统仿真方法,模拟船舶随机到闸和排档过程,考虑多线船闸不同的调度规则,构建了船闸群的系统仿真模型。结果表明:按船舶随机到达顺序依次过闸的规则,船闸总体通过能力相对较优;五线船闸选新闸址建设,且闸室平面尺度宜为340 m×34 m。At present,there are four lanes of locks in Changzhou multi-purpose dam.The down bound cargo volume in 2021 reached 119 million tons and was close to the capacity of locks.In the study of scheme for a new lock,the capacity of existing locks and the new lock should be analyzed in accordance with the cargo volume forecast.The formation of vessels through the lock and the average dead weight tonnage and loading rate of each class of vessels are predicted.Based on discrete event system simulation,a model of lock group is built,simulating the random arrival of vessels and ship arrangement algorithm in lock chamber,and considering different ship distribution rules among multi-lane locks.The results show that the total capacity of lock group is relatively optimal if ship enters lock by its arriving order.Besides,the fifth lock should be built at a new location and plane dimension of 340 m×34 m is suitable for it.
