上海临港新城道路改造海绵城市设计方案

Sponge City Design Scheme of Road Reconstruction in Shanghai Lingang New-city District

以上海海绵城市建设的试点区临港新城内某城市道路改造为研究对象,介绍了城市道路海绵城市建设过程中汇水分区划分、雨水排水组织、海绵设施调蓄量计算、生物滞留带、透水铺装以及附属设施的设计方法。改造道路按照65%年径流总量控制率进行设计,并对项目建成后实际运行效果进行监测,结果表明实际径流总量控制率达96.3%,径流污染物削减率达79%,设计方案满足海绵城市控制目标要求,可为同类项目提供参考。

Taking the road reconstruction of Lingang new-city district in Shanghai,the pilot area of sponge city construction as the research object,we introduced the design methods of catchment division,rainwater drainage organization,sponge facility regulation and storage capacity calculation,biological retention zone,permeable pavement and ancillary facilities in the process of sponge city construction.The reconstruction road was designed according to the 65%annual total runoff control rate,and the actual operation effect was monitored after the completion of the project.The results showed that the actual total runoff control rate reached 96.3%,and the runoff pollutant removal rate reached 79%.The design scheme could meet control target requirements of sponge city,and provide references for similar projects.
