| 摘 要： | 本文提出分区域研究弯曲河道水流动特性的概念，在此基础上，从Ｎ－Ｓ方程出发，对弯曲河道分凸岸和凹岸两个区域分别建立三个维水流速计算模型，并采用摄动法对模型进行了求解，经美国原型观测资料验证，表明模型精度较高，结果令人满意。

| Abstract: | A new method of investigating flow characteristics in channel bends is described inthis paper. The channel to be investigated is divided into a number of regions, then,the three dimensional models for calculating flow velocity in the inner bank region andouter bank region are established separately based on the N-S equation. The solutionof these models can be obtained by using perturbation method. The calculation resultsof the new method agree well with the field data observed in the Fall River, in U.S.A.. |
