摘　　要：传统雨水管渠设计常采用推理公式法进行水力计算,推理公式法包括面积叠加法和流量叠加法2种计算方法。面积叠加法相比于流量叠加法计算更为简单方便,其在雨水管渠规划和雨水管网方案设计阶段经常使用。随着我国城市化率的提高,内涝防治越来越受到业界重视。通过对比分析基于MIKE+的管网模型模拟结果与传统推理公式法计算结果,给出传统推理公式法用于雨水管渠水力计算的优化建议。采用面积叠加法进行工程设计时,建议适当留有富余,进行内涝防治设计时,宜采用模型进行模拟。The reasoning formula method is often used for traditional stormwater pipe design.There are two calculation methods of area superposition method and flow superposition method.The area superposition method is simpler and more convenient than the flow one so that it is often applied in the stage of stormwater pipe planning and network scheme design.With the urbanization rate in China,waterlogging control have drawn more and more attention.By comparing the simulation results based on MIKE+network model with the one by traditional reasoning formula method,some optimization suggestions on the calculation of the traditional reasoning formula method is given.When the engineering is designed by area superposition method,it is recommended to leave appropriate surplus.When the waterlogging prevention and control is designed,the model is advisable to make simulation.
