长江中游藕池口水道航道整治一期工程设计

First phase project design of Ouchikou waterway improvement in the middle reach of the Yangtze River

藕池口水道是长江中游重点碍航水道之一。通过对近期河床演变及碍航特性分析,结合工程建设目标和标准,提出工程平面布置方案。在工程结构设计中尝试了新结构的应用,提出护滩带和护岸结构形式,为类似航道整治设计提供参考。

Ouchikou waterway is one of the key navigation obstructions in the middle Yangtze River. This paper analyzes the recent morphological evolution and navigation obstructing characteristics of this waterway. Combining with the project construction aim and standards, this paper proposes the plane layout of the project. A combination of shoal protection belt and revetment is chosen as the project structure based on the comparison of existing navigation structures which are applied to the to adopt new structures, which may serve as reference waterway regulation. Also, the project structures are designed for the similar waterway regulation design.
