设计洪水地区组成的方法按照规范规定有同频率法和典型年法,典型年法又分峰同倍比放大法和量同倍比放大法,及由此引出的峰、量同倍比放大法等。以北江韶关以上地区设计洪水组成为例,研究设计洪水地区组成的特点,通过对北江上游韶关断面以上洪水的分析,揭示设计洪水地区组成的方法,以及对不同方法计算结果进行分析,提出推荐结果。
The methods of designing flood areas have the same frequency method and typical year method as specified in the code, and the typical year method is divided into the same magnification method and the same magnification method with the same magnification method, and the peak and the magnitudes derived therefrom are the same magnification method Wait. Taking the design flood component in the area above Beijiang Shaoguan as an example, this paper studies the characteristics of the design flood area. Based on the analysis of flood above the Shaoguan section in the upper reaches of Beijiang River, the methods of revealing the design flood area and the calculation results of different methods are analyzed. .
