摘要
岸边流速系数的取值,对渠道流量的计算精度影响很大,但目前对加糙后的渠道岸边流速系数研究还较少。通过对梯形渠道壁面加糙,对渠道岸边流速系数进行初步推求和影响因素分析,并为岸边流速系数的选值提供建议。
The value of shore velocity coefficient has great influence on the calculation accuracy of channel flow.However,there are few researches on the velocity coefficient of channel shore after roughening.In this paper,by roughening the wall surface of trapezoidal channel,the velocity coefficient of channel shore is deduced and the influencing factors are analyzed.Suggestions are provided for the selection of shore velocity coefficient.
