摘　　要：为了充分利用堆场,提高集装箱码头作业效率,对堆场集装箱堆存策略进行了研究,并提出了堆场的横向混合策略.首先基于对堆场独立分布策略与混合分布策略特点分析,确定了混合分布策略的优势.然后从集卡行驶距离和集卡等待时间两个方面,利用概率与数理统计方法对横向混合策略和纵向混合策略进行了对比分析.通过案例计算发现,两种策略集卡行驶距离相等,横向混合策略因能够利用更多场桥,所以该策略下集卡等待时间比纵向混合策略低20.3%,说明了横向混合策略能够提高作业效率.In order to take full advantage of storage yard and improve the operation efficiency in container terminal,the containers storage strategy is study.Firstly,the superiority of mixed storage strategy is explicit based on analysis to independent distribution and mixed strategy’s characteristic.Then,the transverse and longitudinal mixed strategies are comparative analysis in the aspects of the trucks traveling distance and waiting time.The probability and statistic method is used in this process.Finally,calculation result indicates that trucks traveling distances are equal in two strategies.As yard cranes can be used more in transverse mixed strategy than longitudinal mixed strategy,trucks waiting time in transverse mixed strategy is lower 20.3%.This means the transverse mixed strategy can improve the operation efficiency.
