基于触媒理论的城市立交桥下剩余空间设计研究——以贵阳市花果园立交桥下空间为例

Research on the Design of Residual Space under Urban Overpasses Based on Catalyst Theory—Taking the Space under the Huaguoyuan Interchange in Guiyang City as an Example

摘要: “桥下空间”作为城市公共空间的重要组成部分，却一直未能发挥其蕴藏的社会价值，甚至其所造成的城市公共危害，一直被视作社会热点以及难以解决的痛点。本文以“西南第一立交”的贵阳市花果园立交为例，采用实地调研、问卷与访谈等方法对其桥下剩余空间使用情况和使用人群情况及需求进行深入调查，结合问题梳理、市民体验分析及改造诉求，本文引入城市触媒理论，探讨桥下空间作为触媒元素激发相邻其他城市元素产生“链式反应”的激活路径，成为城市“活力触媒”的催化剂，为城市的可持续发展提供持久活力，以期为全国量大面广的城市立交桥下剩余空间改造利用提供参考借鉴和启发。

Abstract: As an important part of urban public space, “space under bridge” has not been able to realize its hidden social value, and even the urban public hazards caused by it have been regarded as a social hotspot as well as a pain point that is difficult to be solved. This paper takes Huaguoyuan Interchange in Guiyang City, the “first interchange in Southwest China”, as an example, and uses field research, questionnaires, and interviews to conduct an in-depth survey on the use of the remaining space under the bridge and the situation and needs of the people who use the space, and combines the combing of the problems, analysis of the public’s experience, and the transformation of the demands, this paper introduces the theory of urban catalyst to explore the activation path of under-bridge space as a catalytic element to stimulate other adjacent urban elements to produce a “chain reaction”, to become a catalyst for urban “vitality catalyst”, and to provide lasting vitality for the sustainable development of the city, so as to provide reference, reference and inspiration for the transformation and utilization of residual space under the overpasses of the country’s large-scale and wide-ranging cities.
