城市轨道交通桥下空间功能更新适宜性研究——以北京地铁5号线为例

Suitability of Functional Renewal of Space Under Urban Rail Transit Bridge:Taking Beijing Metro Line 5 as an Example

以城市轨道交通桥下空间为研究对象,通过田野调查、文献研究等方法,归纳我国城市轨道交通桥下空间现状特征,梳理国内外轨道交通桥下空间功能更新实践,分析北京、上海等城市相关政策,提出城市轨道交通桥下空间功能更新适宜性影响要素,确定功能更新适宜性评价方法。以北京地铁5号线为例,提出不同桥下空间功能更新适宜方向,以期对未来城市轨道交通桥下空间更新改造提供参考。

Taking the space under urban rail transit bridges as the research object,through methods such as field investi-gation and literature research,summarizing the current characteristics of space under urban rail transit bridges in China,sorting out the practical practices of functional renewal of space under urban rail transit bridges at home and abroad,analyzing the relevant policies of cities such as Beijing and Shanghai,proposing the suitability factors affecting the functional renewal of space under urban rail transit bridges,establishing the suitability evaluation method for functional renewal.Taking Beijing Metro Line 5 as an example,the appropriate directions for functional renewal in different under bridge spaces are proposed,in order to provide references for renewal of urban rail tran-sit under bridge space in the future.
