长江上游建库后武汉至安庆段航道条件变化分析
Analysis on navigation channel variation from Wuhan to Anqing of Yangtze River after construction of upstream reservoirs
摘要
Abstract
In order to analyze the possibility of building "golden waterway" in the river reach from Wuhan to Anqing in Yan-gtze River, by the methods of data analysis and mathematical model calculation, the river channel evolution and navigation chan-nel condition variation trend in this reach after the co-operation of 11 reservoirs in the upstream of Yangtze River, such as Xilu-odu, Xiangjiaba, and the Three Gorges reservoir, were analyzed. The research results show that after the operation of the up-stream reservoirs, the overall river regime remains stable with local river regime changes. The beneficial influence of the upstream reservoirs is more than harmful influence. The beneficial aspects are the discharge increase in dry season and erosion of naviga-tion channel by sediment decreasing. The harmful aspects are that the unstable channel caused by erosion of point bar and chan-nel bar, insufficient erosion of shoal in storage period, adjustment of local river regime, etc.关键词
