提高三峡船闸通过能力的船舶运输组织方案

为提高三峡船闸的通过能力,分析了船闸通过能力影响因素,提出提高一次过闸平均吨位是提高三峡船闸通过能力的主要途径,进而提出从提高闸室水深利用和闸室面积利用两个角度来提高一次过闸平均吨位,优化船舶运输组织,即优化船型和过闸船舶组合.研究结果表明,在现有条件下,一次性过闸船舶的组合是2艘5 000t机动船和一个一顶三的驳船队（每驳船载重1 000t）的船队组合,可在闸室水深利用最大化和闸室面积利用最大化的双重提下提高三峡船闸通过能力.

Shipping Organizing Measures to Improve the Throughput Capacity of the Three Gorges Ship Lock

To improve the throughput capacity of the Three Gorges ship lock,the factors influencing the lock capacity are analyzed and then the mean measure is proposed which is to increase the average lockage tonnage.Further,it is proposed that to raise the average lockage tonnage is to enhance the utilization of depth and room area of the lock chamber,which means optimizing the ship type and combination of ships.The study reveals that the optimized combination is two 5 000tonnage ships and three1 000tonnage barges.It can improve the throughput capacity based on the maximum utilization of depth and room area of the lock chamber.
