基于SWMM的老旧小区雨水系统模拟研究

随着我国城市化水平不断提高,城市规模不断扩大,城市洪涝问题日益突出。论文选取东北地区某老旧小区,利用暴雨管理软件SWMM构建了该区域降雨径流模型,模拟了不同重现期设计下的雨水管网运行状况。在此基础上,模拟了低影响开发(LID)措施组合布设的径流控制效果。研究得出,采用LID措施后可以有效控制区域径流总量、削低流量峰值、改善节点溢流情况。

Research on Simulation of Rainwater System in Old Community Based on SWMM

With the continuous improvement of urbanization and the expansion of city scale in China,the problem of urban flood is becoming more and more serious.This paper selects an old community in the Northeast region,uses the storm management software SWMM to construct a rainfall runoff model in this area,and simulates the operating conditions of the rainwater pipe network under different return period designs.On this basis,the runoff control effect of a combination of low-impact development(LID)measures was simulated.The paper concluded that the use of LID measures can effectively control the total regional runoff,reduce the peak flow rate,and improve node overflow.
