使用者视角下高架桥桥下空间的空间建构分析——以福州上渡口立交桥为例

Spatial Construction Analysis of the Space under Viaduct Bridge from the User’s Perspective—A Case Study of Fuzhou Shangdukou Overpass

摘要: 伴随着土地城镇化、人口城镇化以及人均汽车拥有量的提高，中国交通问题日益严峻。城市高架桥作为一种缓解城市交通问题的工具，吸引了众多城市的关注，并在城市中兴起、修建。城市高架桥作为一种缓解城市交通问题的手段，由于自身立体空间的特性也将空间分为桥上空间与桥下空间。桥上空间作为交通通行道路，其空间利用率高，而桥下空间由于自身空间属性的多样性以及规划、参与等原因导致出现空间利用率低甚至荒废的现象，使桥下空间沦为失落空间、畸零空间、灰空间等空间利用类型。因此如何盘活桥下空间是城市立交桥研究中的重要主题。

Abstract: With the increase of land urbanization, population urbanization and per capita car ownership, China’s traffic problems are becoming increasingly serious. As a tool to alleviate urban traffic problems, urban viaduct has attracted the attention of many cities, and has risen and been built in the cities. As a means to alleviate urban traffic problems, urban viaduct also divides the space into the space above the bridge and the space under the bridge because of its three-dimensional space characteristics. The space above the bridge, as a traffic road, has a high space utilization rate, while the space under the bridge, due to its diversity of spatial attributes, planning, participation and other reasons, has a low space utilization rate or even abandoned, resulting in the space under the bridge becoming a lost space, a deformed space, a gray space and other types of space utilization. Therefore, how to revitalize the space under the bridge is an important topic in the study of urban overpass.
