“海绵城市”型地铁设计策略探讨

Discussion on Design Strategy of “Sponge City” Type Metro

目前我国正处在城镇化快速发展时期,由于各种原因,城镇化的过程中没有有效解决地下水资源短缺,水质污染,特别是城市内涝等多种城市水的问题。那么如何使正在国内超过40座城市中大规模建设的地铁工程,具有海绵城市的功能,已经成为一个重要的课题摆在了广大设计者面前。从城市层面出发,针对地铁、海绵城市各自的特点、技术措施,研究将普通的地铁建设成具有海绵功能的"海绵城市"型地铁的可行性,并研究分析在地铁工程的规划、设计和建设过程中,针对不同阶段的、具体的设计策略和方法,为类似工程的设计与建设提供参考,也有利于更好地为城市发展提供服务。

At present,urbanization is developing rapidly in Chin. Due to various reasons,such urban water problems as the shortage of groundwater resources,water pollution,especially city water-logging have not been effectively solved during the process of urbanization. Then,how to conduct large-scale construction of subway projects in more than 40 cities in China,which has the function of sponge,has become an important issue in front of the designers. The purpose of this paper is to study the feasibility of building a conventional subway into a subway with sponge function in perspective of the individual characteristics of the subway and the sponge city,their individual technical measures,and analyze design strategies and methods employed at different stages in the planning,design and construction periods,which are expected to provide references for the design and construction of similar projects,and better serve the urban development.
