某堤防工程设计洪峰流量计算方法

Calculation Method of Designed Flood Peak Discharge of an Embankment Project

文章参照临近库车河的兰干水文站相关数据资料,对盐水沟堤防工程设计洪峰流量计算方法进行分析,重点对模数法、推理公式法、地区综合频率曲线法三种方法推求进行比较,比较结果表明采用洪峰流量模比系数地区综合频率曲线法,更适合作为库车市盐水沟堤防工程设计洪峰流量计算方法。

With reference to the relevant data of the Langan Hydrological Station near the Kuqa River,the calculation method of the design flood peak flow of the Yanshui Ditch embankment project is analyzed in the paper.The comparison of three methods,modulus method,inference formula method and regional comprehensive frequency curve method,is emphasized.The comparison results show that the regional comprehensive frequency curve method of the peak flow modulus coefficient is more suitable for calculating the peak discharge of Yanshui Ditch embankment project in Kuqa City.
