| 摘 要： | 传统的计算天然河道水面线的方法是试算法,迭代法和图解法等,这些方法的缺点是计算量大、精度不高,无法控制全河段误差,将其看作是全河段总计算误差,即一复杂非线性优化最小问题,运用实数编码的加速遗传算法求解天然河道水面线。并与传统的方法相比较,证明该方法具有计算收敛速度快、结果可靠、精度高等优点。

| Abstract: | The shortcomings of the traditional methods that trial-and-error method, approximate solution and iteration method were used to compute the water surface curves of natural watercourses resulting in large amount of calculations, low precise and complex resolving problems. The method that real coding based on Accelerating Genetic Algorithm was applied to calculate the water surface curves of natural watercourses. The results showed that RAGA is much more applicable and precise than those from the traditional methods. |
