中文摘要: 本文研究复式河道断面的流速与切应力分布问题,将纵向动量方程沿水深方向积分,得到流速分布的解析解。考虑断面二次流的影响,在积分过程中采用了三种不同的积分假定,将水深函数代入三个积分方程中求得滩槽连接处水深变化区域内的流速计算公式。应用FCF的实验资料对模型进行验证,发现采用合理的K值比直接采用SKM方法计算能更好的模拟流速和切应力分布;应用FCF的实验资料对三种不同积分假定下的水深变化区域流速和切应力计算公式进行比选,得到了与实测值最为吻合的计算公式。
中文关键词: 复式河道  漫滩水流  流速  切应力
Abstract:A review was made of the methods for determination of the longitudinal dispersion coefficient in natural rivers, especially in river bends, with emphasis placed on the current situation and development trends, i.e. the theoretical formulas, the tracer experiment and the empirical formulas. The applicability of the theoretical formula based on the velocity profile and its further development by researchers at home and abroad were discussed; some new methods for calculation of the longitudinal dispersion coefficient by means of tracer experiment data, and their features were analyzed; some typical empirical formulas were summarized, and some problems which need further research are proposed.
