城市立交桥桥下空间的利用——以郑州市三环内上跨式立交桥为例

Utilization of the Space Under Urban Overpasses:A Case Study of the Overpass Within the Third Ring Road of Zhengzhou City

对郑州市三环内(含三环)的24座立交桥桥下空间的利用现状进行实地调研。调研结果显示:郑州市三环内上跨式立交桥桥下空间的利用形式主要有绿化、停车、交通、商业和设置公共服务设施等;桥下空间的利用存在利用率较低、与周围环境协调性较差、绿化种植较为单一、空间色彩单一且缺乏地域特色、缺乏系统管理等问题。郑州市立交桥桥下空间的合理利用,应充分考虑其周边用地类型及桥下空间的公共服务设施,营造兼具生态功能和美学功能的景观绿化及独具地方特色的桥下空间景观特色,优化完善管理体系,以满足城市居民多元化的生活需求。

A field investigation has been made of the utilization of the space under the 24 overpasses within the third ring road of Zhengzhou city（including the third ring road）. The research results show that the utilization modes of the space under the overpass bridges within the third ring road in Zhengzhou city are mainly facilities for municipal afforestation, parking, transportation, commerce and public services. Meanwhile, there exist such flaws as low utilization rate of space under the overpass bridges, poor coordination with their surrounding environment, unitary planting pattern, monotonous spatial color, lack of regional characteristics and overall management. The reasonable utilization of the space under urban overpass in Zhengzhou city requires a full consideration given to the surrounding land types and the public service facilities under the overpass bridges, thus creating a landscape greening under the bridges with ecological and aesthetic functions and unique landscape features, so as to meet the diversified requirements of urban residents, with its management system optimized and improved.
