为了更好地对一些河流特征的洪峰流量进行统计,本文通过对比2种传统的洪峰流量统计方法:求矩法和三点法,在此基础上进行了优化,并提出了一种新的统计方法:线型三点拟合法。最后,本文分别用求矩法、三点法和线型三点拟合法进行实例分析,应用于秦巴山区汉江流域安康水文测站的洪峰流量统计,并将计算结果进行对比,验证了线型三点拟合法比传统的两种统计方法计算精度更高。
In order to better calculate the peak flow characteristics of some river characteristics, this paper compares two kinds of traditional peak flow statistical methods: the moment method and the three-point method, on the basis of which, we optimize and put forward a new statistics Methods: Linear three-point fitting method. Finally, this paper uses moment method, three-point method and linear three-point fitting method for example analysis, and applies it to the flood peak flow statistics of Han River valley in Qinling-Bashan Han River Basin. Comparing the calculation results, Three-point fitting method is more accurate than the traditional two statistical methods.
