【摘要】：針對三峽蓄水過程中的荊江典型礙航河段,研究了航道整治工程對蓄水過程的適應(yīng)性及工程效果。通過實(shí)測水沙、地形資料,分析了三峽蓄水后荊江河段河床沖淤規(guī)律及航道條件變化,以窯監(jiān)河段為研究對象,采用二維水沙數(shù)學(xué)模型模擬了守護(hù)型工程和調(diào)整型工程對于汛后蓄水過程的適應(yīng)性。結(jié)果表明:在三峽水庫蓄水后"清水沖刷"的前提條件下,守護(hù)型工程對改善航道效果有著積極作用,但需滿足一定條件,主要是淺水道處于較好的演變階段,并且整治目標(biāo)與現(xiàn)狀條件差距不大;而對三峽水庫汛后蓄水過程較為敏感的河段,徹底改善或提高航道條件,需采用一定的調(diào)整型整治工程。研究成果可供三峽工程壩下河段航道整治研究等參考。
[Abstract]:Aiming at the typical obstructing reach of Jingjiang River in the process of water storage in the three Gorges, the adaptability and engineering effect of waterway regulation project to the process of water storage are studied.Based on the measured water and sediment and topographic data, the rules of river bed scouring and silting and the changes of channel conditions in the Jingjiang reach after the three Gorges impoundment are analyzed.The adaptability of daemons and adjustment projects to the process of water storage after flood is simulated by using two dimensional water and sediment mathematical model.The results show that, under the precondition of "clear water scour" after the three Gorges Reservoir impoundment, the daemon project plays a positive role in improving the waterway effect, but it needs to meet certain conditions, mainly that the shallow water channel is in a better stage of evolution.And the target of regulation is not far from the present condition, and the river section which is more sensitive to the storage process after flood of three Gorges Reservoir needs to adopt certain adjustment regulation project to improve or improve the waterway condition thoroughly.The research results can be used as reference for channel regulation under the dam of the three Gorges Project.
