“海绵城市”型地铁设计策略研究

Design Strategy of the “Sponge City” Metro

地铁车辆检修维护及车辆运行均会造成污染物的积累,给城市雨水管网带来负担;在强降雨天气,雨洪可能危害地铁运营安全。因此,实施低影响发展的"海绵城市"型地铁建设模式,提升城市应对自然灾害的良好"弹性"。梳理地铁廊道的构成,对"海绵城市"型地铁设计中的关键问题进行探讨,分析地铁廊道重要构成中的海绵工程适宜区域及应用需求,并进一步提出设计方法及技术路线。对相关工程的建设、运营安全和城市发展有着较大意义。

Subway vehicle maintenance will lead to the accumulation of pollutants, which will consequently cause burden on urban rainwater pipes, and heavy rainfall can endanger the safety of subway operations. Therefore, the research of the low-impact development mode of a "sponge city" metro can protect the water ecological environment and make the subway flexible in dealing with natural disasters. This research clarifies the composition of subways and proposes the design method and technical route after analyzing the application areas of subway corridors, which is of great significance for the construction and operation safety of related metro projects and urban development.
