嘉鱼-燕子窝河段整治工程以固滩稳槽为目的，主要采用护滩带的结构形式，修建在洲滩头部，防止滩体冲刷，以稳定航槽。工程实施后，效果良好，总体河势更趋稳定，复兴洲边滩淤高展宽，燕子窝心滩稳定，稳定了航槽，利于枯水期水流集中，浅区得到较为有效冲刷，碍航程度减轻。工程效果将会随着建筑物功能的继续发挥进一步显现，达到预期目标。%Jiayu-Yanziwo section is a key navigation-obstructing shallow section emerging in the middle reach of the Yangtze River, and it is of great importance to regulate this part of section for the smooth navigation in the middle reach of the Yangtze River. The main purpose of the project is to protect the bottomland and stable the waterway. The project adopts the beach protection structure, which is built on the head of the bottomland to prevent scouring. After the implementation of the project, the situation of the river course becomes more stable, the deposit occurs at the Fuxingzhou point bar, and the bar widens, the Yanziwo beach becomes stable, thus the waterway is stable, the flow concentrates easily in the low water, the shallow ridge is scoured efficiently, and the degree of navigation-obstructing is relieved. It is thought that the effect of the channel regulation project will become more obvious along with the implementation of the structures’ functions and expected goal will be reached.
