长江江阴水道航道水深条件利用研究

Utilization of water depth conditions in Jiangyin waterway of the Yangtze River

针对长江江阴水道航道水深条件充分利用的问题,进行技术可行性及利用方案研究。通过采取平面二维水沙数学模型计算、航道条件核查、潮位累积频率分析等技术手段研究,得出结论:近10年江阴水道航道水深均不小于13.60 m,并且具备一定的可利用潮位,完全具备将吃水提高到12.0 m的技术条件。在此基础上,通过分析研究长江干线已实施的利用航道水深的实例,提出江阴水道航道水深条件利用的2种思路,为深水航道维护管理提供了科学可靠的新方法,推动了航道维护管理创新。

For the full utilization of the water depth conditions of the Yangtze River Jiangyin waterway,we carry out a study on the technical feasibility and utilization plan.Based on the 2D mathematical model calculation,review of waterway conditions,and analysis of tidal level cumulative frequency,we come to the conclusions as follows.In the past ten years,Jiangyin waterway had a water depth of not less than 13.60 m and a certain available tidal level,and it was technically feasible to increase the draught to 12.0 m.Based on the case analysis of the use of waterway depth in the Yangtze River,two ideas for using the waterway depth in Jiangyin waterway are proposed,which provide scientific and reliable new methods for deepwater channel maintenance management,and promote innovation of channel maintenance management.
