长江中游界牌河段过渡段控制工程数值分析研究

Research of the Mathematical Model and Analysis to Regulation Engineering Measures of Jiepai Reaches in the Transition Segment

利用数值模拟及分析的方法 ,针对长江中游界牌河段的水沙特性 ,通过分析研究结合界牌河段过渡段控制工程的平面二维水沙数值计算 ,对界牌河段航道整治后计算河段内的冲淤量、航道变化、流速分布。

A mathematical model and analysis is applied to simulate the channel regulation engineering measures of Jiepai reaches in the transition segment. The model has been finished according to the water-sediment characteristics of Jiepai reaches on the Middle Yangtze River. The research achievements be submitted including erosion and deposition volume, navigation channel change, velocity distribution, current regime in calculation stretch after channel regulation, are useful to design.
