基于Mike Flood模型的老旧小区海绵化改造研究

Study on the Sponge Transformation of Old Residential Area Based on Mike Flood Model

在城市化进程中,由于下垫面透水性及滞水性能的明显降低,减弱了下垫面的雨水调蓄能力。文中以山西太原某老旧小区为例,运用Mike Flood模型模拟了小区海绵化改造效果。结果表明,适宜的海绵措施,能够有效降低小区洪峰流量和径流总量,并能有效改善小区局部积水问题。研究结果可为涵养局部水资源、增强小区防涝能力提供思路,为旧城海绵城市建设提供参考。

In the process of urbanization,The permeability of the underlying surface decreased significantly,which weakens the storage capacity of the underlying surface to rainwater. In this paper,Mike Flood model is used to simulate the effect of sponge reconstruction in an old residential area in Taiyuan,Shanxi Province. The results show that the appropriate sponge measures can effectively reduce the peak flood flow and total runoff,and can effectively improve the waterlogging problems in the community. The research results can provide ideas for conserving local water resources,enhancing the waterlogging prevention ability of the community,and provide reference for the old city sponge transformation.
