长江中游蕲春水道航道整治工程设计与效果分析

Design and effect of Qichun waterway regulation project in middle reaches of the Yangtze River

针对长江中游蕲春水道航道存在的碍航问题,通过对整治工程方案研究,确定了治理目标和整治原则,提出了结构设计思路。进一步优化了护底结构、高滩守护工程的结构形式、护岸加固结构以及水下增设鱼巢砖。通过物理模型动床试验研究了航道工程整治效果,并通过实施后的效果观测验证整治效果良好,整治工程达到了工程建设目标。

In view of the navigation obstruction problem of Qichun waterway in the middle reaches of the Yangtze River,this paper studies the regulation project scheme,determines the regulation objectives and principles,and proposes the idea of structural design.In addition,the paper optimizes the bottom protection structure,the structure type of the high beach protection project,the bank protection reinforcement structure,and the underwater addition of fish nest bricks.It also analyzes the waterway project regulation effect through a movable bed test of the physical model and verifies the regulation effect through effect observation after the project is implemented.The regulation project has achieved the construction goals.
