SWMM在保山市某区雨水管网设计中的应用

Application of SWMM in design of rainwater pipe network for Baoshan city

以保山市隆阳区永昌路雨水管道设计为例,讨论了SWMM的应用。采用芝加哥暴雨模型,将管段流量的模拟结果与径流系数法比较,对管道的设计管径做出调整。在较大重现期情况下,对设计管网进行模拟复核。结果显示,SWMM模型可以为计算雨水设计流量提供可靠的数据支持。该应用说明SWMM能为雨水管道的设计提供新的方法。

Taking the design of rainwater pipe network for Yongchang road Longyang district of Baoshan city as an example, the application of SWMM was discussed. Using Chicago rainstorm model to compare the re-sult of pipe section flow calculated by SWMM simulation method with that by runoff coefficient method, adjusting the design pipe diameter, and then, the simulation re-check of the design pipe network was carried out in larger recurrence interval. The results showed that, SWMM model could provide reliable data for the calculation of de-sign rainwater flow;therefore, it could offer new methods for rainwater pipe network design.
