摘要
东流水道为长江下游典型的多分汊顺直河段,汊道交替、变化复杂,时有碍航情况发生,是长江下游重点碍航水道,也是长江"黄金航道"尺度提升的瓶颈河段。尤其近些年,在经历了西港淤堵、航道调整以及二期整治工程实施后,东流水道演变出现了新变化与新趋势。结合东流水道最新实测资料,分析其演变特点及碍航特性,揭示汊道变化的影响因素,并建立二维水沙数学模型,预测未来东流水道的演变趋势。在此基础上,提出主要维护对策及措施,为同类水道的航道维护与整治提供参考。
Dongliu waterway is the typical multi-branch straight reach in the lower reach of the YangtzeRiver. It is the key navigation-obstruction waterway in the lower reach of the Yangtze River and the bottleneck ofnavigation improvement in the Yangtze ＂Golden Waterway＂. Recently, experiencing the ＂west channel clogging,waterway adjustment and implementing the second phase of the regulation project, Dongliu waterway＇ s evolutionappeares new changes and new trends. According to the latest measured data, this study analyzes the evolutioncharacteristics and navigation obstructing characteristics, reveals the influential factors of channel change,establishes two dimensional mathematical model of water and sediment, and predicts the evolution trend of Dongliuwaterway in the future. Based on that, the study proposes the main maintenance countermeasures and suggestions,which provides reference for the waterway maintenance and waterway regulation of the same kind.
