【摘要】：為給長江中游周天河段航道整治提供基礎(chǔ)性技術(shù)支撐,對該河段開展了河床演變及礙航特性研究�；谝延醒芯砍晒�,采用實測資料分析的方法,研究河段近期演變規(guī)律、航道存在的問題及礙航特性,并對河床演變和航道條件變化趨勢進行預(yù)測。結(jié)合該段航道整治目標(biāo),提出航道治理的總體思路。
[Abstract]:In order to provide basic technical support for channel regulation in the middle reaches of the Yangtze River, the river bed evolution and navigation hindrance characteristics were studied.Based on the existing research results, using the method of analysis of measured data, this paper studies the recent evolution law of the river reach, the problems existing in the channel and the characteristics of hindrance to navigation, and forecasts the evolution of the riverbed and the changing trend of the waterway condition.Combined with the target of waterway regulation, the general idea of waterway regulation is put forward.
