摘　　要：为了缓解船舶过闸需求和船闸服务能力之间的矛盾,以内河多线船闸为研究对象,利用元胞自动机原理建立了包括顺直段和弯曲段的航道船舶交通流模型,在考虑闸室分配规则、BL排样算法和多闸室并行调度规则的基础上建立了多线船闸调度优化仿真模型,并利用内河航运系统船舶交通组织方法,将船闸与航道两个子模型看成系统模型中的节点和通道,建立了船闸-航道一体的多线船闸系统调度优化模型。以长洲水利枢纽四线船闸为研究对象,根据建立的船舶交通流模型和多线船闸系统调度优化仿真模型对航道船舶交通流时空分布特性、船闸调度优化指标等进行了仿真分析。试验结果表明:船舶上下行平均延误较实际分别降低了10.3%、8.8%,上下行闸室利用率分别提高了7.4%、7.1%。A cellular automata-based multi-line ship lock traffic flow model is developed for optimizing the operation performance of the lock.The model is designed for both straight approaching channel and curved approaching channel and integrated with lock chamber allocation rule,BL layout algorithm and the rules for lock chamber parrel running.The ship lock part and the channel part of the model are defined as the node and the path in the system respectively.The model is used to investigate the four-line ship lock of Changzhou hydraulic complex.The spatiotemporal distribution and the index of ship lock running optimization level are calculated and analyzed.The simulation shows that the optimization can decrease the up-going and down-going delay by 10.3% and 8.8% respectively and raise the running efficiency of lock chamber by 7.4% and 7.1% respectively.
