摘要
迭代法是求解梯形明渠临界水深的基本方法之一.通过对临界水深方程进行数学变换,采用Steffensen迭代法进行计算.计算数据表明,迭代一次即可得出精度很高的临界水深值.该法不依赖图表,迭代式简明直观,计算便捷,精度很高,可供工程实际参考应用.
Iteration method is one of the basic methods of computing the critical water depth of trapezoid open channel.This paper presents a new way of calculating critical water depth of trapezoid open channel by Steffensen iteration method.The method is simple,convenient and accurate and the users don't need a table or a figure to determine the empirical coefficients.
