长江中游藕池口水道河床演变及航道条件分析

藕池口水道位于长江中游下荆江首端,河床演变十分复杂,揭示其演变机理并针对性地提出相应的治理措施十分必要。藕池口水道在下荆江具有一定的代表性。从实测资料出发,分析藕池口水道的河床演变特点,揭示其滩、槽演变规律,并通过重点分析航道条件,提出治理措施,可为后续深入研究荆江河段河床演变、碍航特性及航道治理提供参考。

River-bed evolution and navigation condition of Ouchikou waterway in the middleYangtze River

The upstream reach of the lower Jingjiang stretch of the middle Yangtze River (from Guchangdi to Beimenkou), alternatively the Ouchikou wterway is analyzed based on the field data. Because of the complicated fluvial process, it is necessary to reveal the process mechanisms and present regulation methods. Based on the measured data, this paper analyses the characteristics of fluvial process and reveals the process mechanisms of bars and pools. Through the analysis of waterway condition, the regulation methods are suggested. The results may serve as a reference for future study of the Jingjiang stretch.
