船舶成组通过大型船闸匹配运行方式与工艺研究

Matching running mode and technology of ships passing through large ship locks in groups

针对三峡—葛洲坝梯级枢纽通航建筑物长期处于满负荷运行状态,船舶待闸数量大、时间长的问题,国家正研究推进三峡水运新通道和葛洲坝航运扩能工程,葛洲坝航运扩能工程施工期将对葛洲坝船闸通过能力造成较大影响。为了提升施工期葛洲坝船闸通过能力,开展电动智能工作船牵引船舶成组过闸研究,提出船舶成组通过葛洲坝1#、2#船闸的3种运行方案,并进行理论计算分析,从安全、效率、经济等多维度进行综合论证,得出葛洲坝1#、2#船闸双向匹配循环运行方式为较优方案,船舶成组过闸可显著提升船舶进出闸效率,提高葛洲坝航运扩能工程施工期间的通过能力。

In view of the problems that the navigation buildings of the Three Gorges-Gezhouba cascade hub are in full load operation for a long time and the number of ships waiting for locks is large and the time is long the country is studying to promote the Three Gorges water transport new channel and Gezhouba shipping capacity expansion project.The construction period of the Gezhouba shipping capacity expansion project will have a significant impact on the passing capacity of the Gezhouba ship lock.To improve the passing capacity of Gezhouba shiplock during the construction period the research is carried out on the electric intelligent working boat towing ships to pass through the lock in groups.Three operation schemes for the group passing through the 1#and 2#shiplocks of Gezhouba are proposed and theoretical calculations and analysis are conducted and comprehensive demonstration is carried out from multiple dimensions such as safety efficiency and economy.It is concluded that the bidirectional matching cycle operation mode of Gezhouba 1#and 2#shiplocks is the optimal scheme and the group passing of ships through the lock can significantly improve the efficiency of ship entry and exit and improve the passing capacity of the Gezhouba shiplock during the construction period of the Gezhouba shipping capacity expansion project.
