摘　　要：介绍道路雨水汇水量、雨水口明渠流与雨水箅子最大过流量计算公式。以40m红线道路断面形式为例,验证假定雨水口间距的合理性,并根据雨水口布置间距计算公式提出其他道路断面形式下雨水口的理论计算布置间距,为廊坊市雨水口间距布置提供一定的理论计算参考。The paper Introduces the formula for calculating the rainwater catchment volume,the open channel flow of the rainwater outlet and the maximum flow of the rainwater grates.Taking the form of 40 m red line road section as an example,the rationality of the assumed spacing between the rain inlets is verified,and the theoretical calculation of the arrangement spacing of other road sections is proposed according to the formula of the arrangement spacing of the rainwater inlet,which provides a theoretical calculation reference for the layout of the rainwater inlet spacing in Langfang city.

关 键 词：雨水口流量 径流系数 布置间距 明渠均匀流
