摘要
针对我国城市目前存在的一系列严重内涝问题,采用"LID(低影响开发)+GSI(绿色基础设施)+传统技术"组合模式的新理念,进行了城市道路排水工程设计。以广州市天河区一条城市市政道路工程的排水设计为例,介绍了排水工艺设计、道路横断面设计、渗排一体化系统设计、渗透井设计、工程主要经济指标及与传统城市道路排水工程相比较所体现的优势,并对工程实施后的效益进行了分析评价。该工程作为广州首例将该理念用于城市道路排水工程设计的项目,可为今后类似工程提供参考。
To address a series of serious problems of waterlogging in cities of China, a new concept of low impact development （LID） ＋ green stormwater infrastructure （GSI） ＋ traditional techniques was used in design of road drainage project. Combined to the drainage design of a municipal road in Guang- zhou Tianhe District, the drainage process design, road cross-section design, infiltration and drainage system design, permeable well design, main economic indicators and the advantages over traditional road drainage projects were introduced, and the benefits generated by the project were analyzed. As the first project using the new concept in drainage design of the municipal road in Guangzhou, the project can provide reference for similar projects.
