摘要
近年来长江上游来沙量明显减少,水沙动力条件的变化导致福山水道的淤积萎缩速率有可能会加快。铁黄沙沙体缺乏有效控制,仍然存在被冲散的可能。为了统筹兼顾河势控制、深水航道建设、水土资源开发利用以及望虞河口引排水安全等各方面的需求,铁黄沙整治工程应运而生。通过对工程局部河段河床演变进行分析,探讨整治工程对航道的影响,对维护长江下游深水航道的稳定性有重要意义。
In recent years, the Yangtze River sediment has reduced significantly, and the changes of hydrodynamic conditions of water and sediment may accelerate the siltation atrophy rate of Fushan waterway. Due to the lack of effective control of Tiehuangsha, there still exists a possibility of being broken up. To meet various needs, we carry out the Tiehuangsha regulation project. Based on the analysis of the riverbed evolution, we explore the impact of the regulation project on the waterway, which is of great significance on the maintenance of the stability of the deep channel in the Yangtze River.
