长江中游戴家洲水道6.0 m航道整治工程效果分析

Effect analysis of 6.0 m waterway regulation project of Daijiazhou channel in middle reaches of the Yangtze River

戴家洲水道位于长江中游武汉—安庆段,是长江中游分汊河段中重点碍航滩段之一。近年来随着长江沿岸经济的发展,对航道水深也提出了更高的要求。为达到更高尺度的水深要求,航道部门于2018年对该水道实施6.0 m航道整治工程。工程实施后定期效果观测资料的分析表明:6.0 m航道整治工程实施后,池湖港边滩和乐家湾边滩冲刷发展得到限制,构建了良好的滩槽格局,直水道航道条件得到改善,基本实现了6.0 m航道畅通的治理目标。

Daijiazhou Waterway is located in the middle reaches of the Yangtze River from Wuhan to Anqing,and it is one of the key beach sections that affect navigation in the branches of the middle reaches of the Yangtze River.In recent years,as the economy develops along the Yangtze River,higher requirements have also been placed on the water depth of the waterway.To meet the higher-scale water depth requirements,the waterway department implemented the 6.0 m waterway regulation project for the waterway in 2018.After the implementation of the project,regular observation data of effects is analyzed to evaluate the remediation effects.The results show that the implementation restrains the continuous scouring development of the Chihu Port Beach and the Lejia Bay Beach.It constructs a good beach-groove pattern and improves the waterway conditions of the straight channel,basically unblocking the 6.0 m channel.
