长江下游黑沙洲水道航道整治二期工程模型试验研究
发布时间：2019-03-02 13:13
【摘要】：黑沙洲水道是长江下游重点碍航水道之一。一期整治工程实施后,航道条件得到改善,但遇不利水文条件时,航道淤积严重,需进一步实施二期整治工程措施缓解航道维护压力。通过分析该河段的河道演变和碍航特征,采用动床模型试验的研究手段,对航道整治二期工程初设阶段的工程方案进行了系统研究,提出推荐方案。推荐方案实施后,黑沙洲水道河势基本保持不变;南水道右槽航道分流比增加,浅区冲刷,航道条件得到有效改善。
[Abstract]:Heishazhou waterway is one of the key navigation channels in the lower reaches of the Yangtze River. After the implementation of the first regulation project, the waterway conditions have been improved, but when the adverse hydrological conditions are encountered, the channel siltation is serious, so it is necessary to further implement the second stage regulation engineering measures to alleviate the maintenance pressure of the waterway. Based on the analysis of the channel evolution and navigation hindrance characteristics of the reach, a systematic study on the project scheme in the initial stage of the second stage of the waterway regulation project is carried out by using the method of moving bed model test, and the recommended scheme is put forward. After the implementation of the recommended scheme, the river regime of the Heishazhou waterway remains basically unchanged, the diversion ratio of the right channel of the south channel increases, the shallow area scours, and the channel conditions are effectively improved.
