中文摘要:
      船闸通过能力是平陆运河开发的核心问题之一。基于货运量和过闸船型预测结果,分析影响船闸通过能力的因素;采用计算机模拟技术,建立船舶进闸的排队仿真模型,得出一次过闸平均吨位、一次过闸船舶数及闸室利用率3个关键参数,据此分析并比较合理尺度下大、小船闸分工运行和双线船闸随机运行两种模式的船闸通过能力;并在大、小船闸分工运行模式下,对小闸通过能力与船舶载货量进行闭合调整。结果表明,平陆运河须同时建设双线船闸,当1 000吨级船舶艘次比较大时,大、小船闸分工运行模式的船闸通过能力更大,且远期部分1 000吨级船舶须从大闸通过才能使小闸通过能力满足运输需求。
英文摘要:
      The lock capacity is one of the core concerns for the Pinglu Canal. This paper analyzes the factors influencing the lock capacity. Through computer simulation,three main indicators,i.e. the average total tonnages per lockage,the average vessel number per lockage,and the occupancy rate of the lock chamber,are acquired,and according to which,the lock capacities of the two operation modes including separate operation of large and small locks with a reasonable scale and random operation of the double-lane lock are compared. Moreover,the lock capacity and ship’s freight tonnage under the separate operation mode are adjusted. The result shows that double-lane locks shall be built at the same time,the separate mode provides a bigger capacity when the 1 000 DWT vessel accounts for a larger proportion,and some 1 000 DWT vessels have to pass through the big lock to ensure that the small lock’s capacity meets the transport demand.
