摘　　要：城市明沟有承接管道排水及区域排涝等功能,但汇流区域较小的明沟排涝流量如何确定方法不一。本文采用三种流量计算方法对郑州市金洼干沟进行流量规模确定,对三种计算结果进行对比分析,结果表明,2023年暴雨强度推算公式更适合,但该计算结果较大,与现状河道过流不匹配,应采用综合治理措施来达到规划目标。本文的计算方法可为相关明沟排涝规模确定提供参考。Urban open ditches serve functions such as drainage through connecting pipelines and regional flood control.However,the methods for determining the drainage flow of open ditches with smaller catchment areas vary.This paper employs three flow calculation methods to determine the flow scale of the Jinwa Main Ditch in Zhengzhou,and compares the results of these methods.It results indicate that the rainfall intensity estimation formula for 2023 is more suitable,but the calculated flow is larger than the current river flow capacity,indicating a mismatch.Comprehensive management measures should be adopted to achieve the planning goals.The calculation methods presented in this paper provide a reference for determining the drainage scale of related open ditches.
