【摘要】:黑沙洲水道是長江下游重點礙航水道之一。一期整治工程實施后,航道條件得到改善,但遇不利水文條件時,航道淤積嚴(yán)重,需進(jìn)一步實施二期整治工程措施緩解航道維護(hù)壓力。通過分析該河段的河道演變和礙航特征,采用動床模型試驗的研究手段,對航道整治二期工程初設(shè)階段的工程方案進(jìn)行了系統(tǒng)研究,提出推薦方案。推薦方案實施后,黑沙洲水道河勢基本保持不變;南水道右槽航道分流比增加,淺區(qū)沖刷,航道條件得到有效改善。
[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.
