摘　　要：针对圆形断面特征水深求解困难的问题,采用Matlab中查找函数零点命令fzero及编程,通过具体工程实例,给出圆形断面临界水深、正常水深和收缩水深的求解方法。与传统方法相比较,该方法直接应用特征水深的理论公式进行编程计算,程序简洁明了,操作简单,效率高,精度高。Aiming at the difficulty of solving the characteristic water depth of the circular section,the article is searching for the function zero command fzero and the programming by use of Matlab,Through the specific engineering examples,it has been shown the solution method of the critical water depth,normal water depth and contracted water depth of the circular section.Compared with the traditional method,this method directly applies the theoretical formula of characteristic water depth for programming calculation.The program is simple and clear,the operation is simple,high efficiency,and high accuracy.
