摘要
城市排水管网作为城市重要的基础设施,担负着城市生活污水、工业废水的收集以及雨水排除的任务。本文以哈尔滨市道里区某一条街道为研究对象,在SWMM模型的基础上建立了管网排水模型,根据一年一遇的强降雨数据进行模拟计算,得到溢流节点共20个,溢流峰值流量在0.009—0.272 m_(3)/s之间,溢流总量在9—318 m_(3)之间;瓶颈管段有50个,其中管段承载时长在0.09—1.74 h之间。最后针对构建的模型进行评估,总结出SWMM管网排水模型原理、模拟过程并给出了实施建议。
As an important infrastructure of the city,urban drainage network is responsible for the collection of urban domestic sewage,industrial waste water,and rainwater drainage.In this paper,a street in Daoli district of Harbin city is taken as the research object.Based on the SWMM model,the drainage model of pipe network is established.According to the once-in-a-year heavy rainfall data,a total of 20 overflow nodes are obtained,the peak flow of overflow is between 0.009 m_(3)/s and 0.272 m_(3)/s,and the total amount of overflow is between 9 m_(3) and_(3)18 m_(3).There are 50 bottleneck pipe sections,in which the bearing time of pipe section is between 0.09 h and 1.74 h.Finally,the model is evaluated,the principle and simulation process of SWMM pipe network drainage model is summarized,and the implementation suggestions are given.
