长江陆溪口水道航道整治方案研究

Study on Regulation Scheme to evolution of Luxikou Waterway of Yangtze River

陆溪口水道是长江中游的重点浅水道之一,由于汊道的兴衰交替,航槽也相应变迁,另外由于直港进口、中港汊道中部及出口处碍航浅滩的存在,导致航道维护困难。根据河床演变特点,确定稳定洲滩、增加直港进口分流、改善直港航行条件的工程措施。近十年河势相对稳定,但中港仍在持续弯曲发展,应抓住有利时机对该水道加以整治。

Luxikou River is one of shallow waterway in middle reach of Yangtze River.The navigational channal changes with the fluvial process of river. In the meanwhile,the shoals exist at the entrance of Zhigang and Zhonggang branch. It's difficult to maintain the waterway. The depth of waterway is kept upon 3.2 meters,and the carrying capacity of tank barge must be decreaed to pass through.For the demands of constructing the main channel of Yangtze River,the measements for stabilizing and improving must be carried out as soon as possible.
