摘要
为了有效地利用历史调查资料,提高水文频率计算的精度和稳定性,基于MATLAB GUI平台开发了适用于具有历史特大值序列的P-Ⅲ型曲线适线软件,实现了频率曲线绘制、参数矩法初估、目估适线调整、设计频率与设计特征值相互查询等全部常用功能。与传统实现方法的对比表明:该软件能够快捷、高效地进行频率计算,便于调整参数以提高拟合度,大大提高了水文频率计算的工作效率。
In order to improve the hydrological frequency calculation precision and stability, a new frequency software which can be used toanalyze P-Ⅲ distribution was developed based on MATLAB GUI platform. The software carried out distribution function parameter estimationwith moment method, estimating fitting line,frequency curve drawing and frequency design value between each other query. Applicationresults show that the software can be efficiently computed while being able to adjust the parameters according to the fitting accuracy byhumancomputer interaction. The software greatly reduces hydrological frequency calculation work. The results can fully meet the demand ofprobability analysis in hydrological research of engineering.
