Abstract: Twin 40 feet quay cranes are used to improve handling efficiency in container terminals. However, the recommended value of container trucks quantity is not given in national norms for the planned port area equipped with 40 feet quay cranes . Based on the operating characteristics of the twin 40 feet quay cranes, a microscopic traffic simulation model was built for a container terminal with twin 40 feet quay cranes in Dalian to address the trucks allocation problem. Operations in container terminal apron, yard and port gate area were included in this model. By running the simulation model, the traffic operation rule in container terminals with twin 40 feet quay cranes and the relationship between container trucks allocation quantity and the average handling efficiency of twin 40 feet quay cranes can be observed. Lastly, the recommended optimal quantity of container trucks allocated are provided , which can provide experience and reference for planning of container terminals to be equipped with twin 40 feet quay cranes.

摘要： 集装箱船舶大型化促使双40英尺岸桥不断投入使用，然而我国现行规范对于面向双40英尺岸桥的集装箱港区规划期的集卡配置数量尚未给出推荐取值。基于系统仿真理论，考虑集装箱港区双40英尺岸桥的作业特点，以大连某大型集装箱港区为例，利用VISSIM仿真软件建立了包括码头前沿、堆场以及港区大门在内的集装箱港区陆域微观交通系统仿真模型。通过运行仿真模型获得仿真结果，分析配备了双40英尺岸桥的大型自动化集装箱港区内部交通运行规律，得到了大连某大型集装箱港区的双40英尺岸桥平均装卸效率与集卡配置数量间的关系，给出了该港区的在规划期的集卡配置建议，为采用双40英尺岸桥的集装箱港区在规划期的集卡配置提供经验与参考。
