| 摘 要： | 在前人研究的基础上,明确了河流最佳弯道的概念,认为河道最佳弯道形态不仅与水流条件有关,也决定于河床周界条件包括河岸组成粒径和沙粘土组成.综合水流动力条件和河床组成因子,初步建立了河道最佳弯道形态曲率半径的表达式,并结合汉江中下游弯道实际,建立了该河道最佳弯道形态的经验公式,该公式对于水利工程和航道工程中弯道形态的确定具有一定的参考价值.

| Abstract: | Based on field data and former research,the perfect morphology of meandering river is studied.The perfect morphology of meandering river was influenced not only by flow conditions including flow discharge and slope of river,but also influenced by the constitute and median diameter of river bed.The expression of curvature semidiameter is formed.Based on the field data of the middle and lower reaches of the Hanjing River,an empirical formula is developed.This empirical formula may be helpful both in river engineering and waterway improvement. |
