【摘要】：为给长江中游周天河段航道整治提供基础性技术支撑,对该河段开展了河床演变及碍航特性研究。基于已有研究成果,采用实测资料分析的方法,研究河段近期演变规律、航道存在的问题及碍航特性,并对河床演变和航道条件变化趋势进行预测。结合该段航道整治目标,提出航道治理的总体思路。
[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.
