| 摘 要： | 目前计算梯形明渠的临界水深的常用方法有试算法、图解法、近似公式法和迭代法,这些方法均有计算量大、精度不高等缺点。因此,采用基于实数编码的加速遗传算法(RAGA)来求解,通过实例应用并与传统方法相比表明,RAGA的适应性强,计算精度高,是一种非线性全局优化的好方法。

| Abstract: | At present, the traditional trapezoid section are trial-an-error method, large calculation and rough precision. For method for calculating critical water depth of open channel with approximate solution and iteration method, whose shortcoming are the reason, in this paper, the method that real coding based on Accelerating Genetic Algorithm is applied to the solution. The result of application examples what compared with that of other methods shows that RAGA is a much more applicable and precise than traditional methods which on the solution of nonlinear optimal problem. |
