摘要
船舶大型化对船闸节点通过能力的增长既有利也有弊,针对船舶大型化对船闸通过能力的动态定量影响进行研究。通过建立基于现实规则的船闸数值排档模型,结合构建的大型化船舶发展趋势序列,计算得出船舶大型化后的过闸载质量、过闸船数和闸室面积利用率等船闸通过能力关键指标的变化。结果表明,船舶的大型化对过闸能力的提高并非全部为有利影响,呈现总体增长,局部跌坎下降的趋势。结合标准化的大型化能有效提高通过能力。
Ship large-scale may have advantages and disadvantages on increasing of passing capacity of lock node,so we study the dynamic and quantitative influence of ship large-scale on ship lock's passing capacity. By the ship lock numerical displacement model based on the actual rules,we calculate the changes of key indexes of the ship lock's passing capacity combined with the established large ship development trend sequence,such as the load mass,number of ships and the area utilization ratio of the lock chamber,etc. The results show that the ship large-scale has not all positive effects on the improvement of lockage capacity, and there is a trend of overall growth and partial decline. The combination of standardization and large scale is an effective strategy to improve the passing capacity.
