新疆白杨河巴依托海渠首除险加固工程洪水分析计算

Flood Analysis and Calculation of the Head of the Canal Reinforcement Project in the Baiyang River,Bayituohai,Xinjiang

随着渠首工程建设的日益增多,渠首工程质量要求越来越高。洪水分析计算在渠首设计中起到了至关重要的作用,结合巴依托海渠首工程实例进行分析,通过长短系列统计参数对比、莫比系数累积平均曲线、模比系数差积曲线,对资料的"三性"进行了分析,采用P-Ⅲ型曲线适线,确定参证站统计参数,进行洪峰流量计算,其设计洪水分析及计算方法,可供同类工程参考。

With the increasing number of canal head projects,the quality requirements of canal head projects are getting higher and higher.Flood analysis and calculation have played a vital role in the design of the canal head.Based on the analysis of the Bayituohai Canal Head Project,the"three characteristics"of the data are analyzed through the comparison of long and short series of statistical parameters,the cumulative average curve of Moby coefficient,and the difference product curve of modulus coefficient.The P-Ⅲcurve fits the line,determines the statistical parameters of the participating stations,and calculates the peak discharge.The design flood analysis and calculation method can be used as a reference for similar projects.
