摘　　要：传统雨水管渠系统设计计算采用推理公式法,而雨水管渠系统日常运行模拟中考虑时变降雨、降雨损失变化等情况时,需要采用雨水管理模型。与推理公式法相比,雨水管理模型需要更多的数据输入,且需要适当处理径流系数和集水时间。首先提出了雨水管理模型模拟推理公式法设计计算管渠系统的方法,然后通过算例讨论了推理公式法和雨水管理模型模拟的计算结果。小型算例说明,雨水管理模型可近似再现推理公式法的计算结果。The rational formula method is widely used in the traditional design and calculation of storm sewer system. However, stormwater management model is needed when time-varying rainfall and rainfall loss change are considered in the daily operation simulation of the storm sewer system. Compared with the rational formula method, the stormwater management model needs more data input, and requires to deal with the runoff coefficient and catchment time properly. The paper firstly introduced the application of simulation rational formula method of stormwater management model in design and calculation of sewer system, and then discussed the calculation results of rational formula method and stormwater management model simulation through an example. The small example showed that the stormwater management model approximately reproduced the calculation results of the rational formula method.
