摘要
为帮助水文工作者提高绘制频率曲线的效率和精度,本文以兴国县2000—2017年的降水量资料为依据,详细阐述了在Excel软件辅助下,绘制频率格纸,运用适线法求解兴国县降水量频率曲线的方法。通过该方法绘制的水文频率曲线图不仅整洁美观,而且精度较高。该工作方法可以在水文计算中更简洁、精准实用地推求设计降雨量、设计洪水、枯水流量频率等。
In order to help hydrologists improve the efficiency and accuracy of drawing frequency curve,this paper,based on the precipitation data of Xingguo County 2000—2017,elaborated the method of drawing frequency grid paper with the help of Excel software,and solving the precipitation frequency curve of Xingguo County by using the line fitting method.The hydrological frequency curve drawn by this method is not only neat and beautiful,but also has high accuracy.It more conveniently,concisely,accurately and practically working method for calculate amounts of design rainfall,design flood,low water flow frequency and so on.
