提高三峡船闸运行效率的船舶过闸方式研究

Research on passing mode to improve efficiency of Three Gorges Ship-lock

为充分发挥长江"黄金水道"的作用和优势,提高三峡船闸的通过能力,通过分析三峡船闸近5年的运行数据,对某些关键运行参数与设计值进行比较后发现,现行过闸方式的进闸时间和移泊时间过长,是导致船闸实际日运行闸次低于设计值的主要原因。在此基础上,提出在船闸上下游水域设置虚拟闸室的方案,经实船测试资料统计分析,研究了设置虚拟闸室的必要性和船队过闸方案理论上的可行性。可为进一步提升三峡船闸的日运行闸次和通过能力提供理论支撑。

In order to improve the shipping capacity of Three Gorges Ship - lock and give full play to the ＂ golden waterway＂ advantages of Yangtze River, according to the operation data of Three Gorges Ship - lock in recent five years, some of the key op- erating parameters are compared with designed ones. It is pointed out that the efficiency of locks is lower than designed value be- cause of the long time spent in ship shifting and entering into shiplock by the current passing mode. On this basis, the program of setting up virtual chambers in the upstream and downstream waters of Three Gorges Ship - lock is proposed. By the analysis of the statistical data of real shipping test, the feasibility of the fleet lockage program and the necessity of virtual chambers are studied, which may further increase the daily running times of locks and improve the lock capacity of Three Gorges ship - lock.
