摘要
结合某城市快速化道路改造工程实例,通过控制径流总量、控制径流污染及雨水资源利用等方式,因地制宜选取相应海绵城市适宜理念技术,使道路建设完成后水文特征接近道路改造前。通过研究分析发现,海绵城市理念应用在城市快速化道路中可以有效提升雨水利用率,降低面源污染,提高城市排水能力,对促进城市发展有较大的意义。
This article takes an urban expressway renovation project as an example.The project finally makes the hydrological characteristics after the completion of road construction close to that before road reconstruction by controlling the total runoff and controlling runoff pollution and rainwater resources utilization.It is found that the application of the concept of sponge city can effectively improve the utilization rate of rainwater and the drainage capacity of the city,meanwhile,it can reduce the pollution of non-point source,which is of great significance for promoting urban development.
