中文摘要：

随着港口现代化与船舶大型化的发展,沿海集装箱港区的泊位装卸效率也在迅速提高,单线航道利用率也受到了影响。基于计算机仿真技术,建立沿海集装箱港区船舶进出港作业系统仿真模型,着重研究泊位装卸效率对单线航道利用率的影响规律,为港口规划和建设决策提供参考。研究结果表明：提升泊位装卸效率可提高单线航道利用率,港区在提升泊位装卸效率来增加港口通过能力的同时,要兼顾其对航道利用率的影响,否则将会导致航道利用率过高,造成航道拥堵,降低航道服务水平等级。对于实例中的港区规模,建议装卸效率提升幅度不宜超过13%。

英文摘要：

With the development of modernized port and large-scale ships,the handling efficiency of coastal container terminal is increased rapidly,which has a great impact on the channel utilization ratio.Therefore,the relationship between port handling efficiency and channel utilization ratio is studied emphatically using system simulation technology.The results show that increasing the handling efficiency appropriately can increase the utilization;While improving the handling efficiency to increase the port capacity,we must consider the impact on the channel utilization,otherwise it will result in high channel utilization,channel congestion and reduce the level of channel services.For the scale of berths in the instance,the proposed handling efficiency rate should not exceed 13%.
