摘　　要：目前在许多城市的防洪规划中,水利部门和市政部门采用的河道流量计算方法均不能满足河道设计流量计算的要求。该文参照等流时线法的原理,提出一种近似的计算城市排涝河道设计流量的方法,可供从事城市河道设计的专业人员参考。At present in the flood control planning of many cities, the river flow calculation methods of the water conservancy and the municipal department can not meet the requirements of the river design flow calculation. Referring the principle of the equal-flow-time curve process, the article puts forward a method approximately to calculate the design flow of the urban drainage river, which can be referred for the professional members undertaking the design of the urban rivers.

关 键 词：河道设计流量 城市防洪规划 近似计算
