长江下游湖口至浏河口河段支汊航道技术等级与航道尺度研究

Study on dimension and classification of tributary channel in Lower Yangtze River

在对长江下游湖口至浏河口河段各支汊航道自然条件核查及利用现状分析的基础上,分析下游支汊航道可资利用的资源及其开发利用的价值与可行性,结合需求分析,兼顾已有外部条件,以《内河通航标准》为依据,参照相关航道定级标准及规范,提出了确定支汊航道尺度与技术等级的基本原则和方法,并提出了长江下游各支汊航道的技术等级和维护尺度。

Based on verification and utilization of natural condtions of the branch channels in Hukou-Liuhekou section in the lower reaches of the Yangtze River, the value and the feasibility of the resources available for use were analyzed in this paper. In combination with the requirement analysis and on the basis of Navigation Standard of Inland Waterways and the relevant channel grading standard, the basic principles and methods of determining the channel dimensions and classes of branch channels were put forward, and the channel maintenance dimensions and the channel classes of branch channels in the lower reach of the Yangtze River were presented.
