摘要 为了提升城市排水设计水平,本文基于海绵城市理念,分析了绿色雨水基础设施的设计原则和设计目标及其对土壤透水特性、地形坡度、地下水位、地表水体等的具体要求。同时,从绿地分布、街区道路、城市建筑等方面探讨了绿色雨水基础设施的设计策略,并以某城市道路改造项目为研究对象,利用SWMM模型计算了不同工况下的地面径流,对绿色雨水基础设施的设置效果进行了评价。 In order to improve the design level of urban drainage facilities,based on the concept of Sponge City,this paper analyzes the design principles and design objectives of green rainwater infrastructure as well as its specific requirements for soil permeability,terrain slope,groundwater level,surface water body,etc.At the same time,the design strategy of green rainwater infrastructure is discussed from the aspects of green space distribution,block roads,urban buildings,and so on.Taking a urban road reconstruction project as the research object,the SWMM model is used to calculate the surface runoff under different conditions,and the setting effect of green rainwater infrastructure is evaluated.
