| In recent decades,with the rapid development of China’s urbanization process,the scale of urban transportation has been expanding,and its high-efficiency transportation viaducts have also increased.Although the viaduct can carry huge traffic flow and relieve traffic pressure,for the city,the viaduct causes strong intrusion into the urban space,and the viaduct constantly affects the spatial environment of the original location in terms of scale,shape,and site selection.Combined with the uneven distribution and underutilization of the quality of public space in domestic cities,through the study of the use of space under urban viaducts,the quality of urban space is optimized to a certain extent,bringing more convenience to surrounding residents and meeting people’s daily life needs.At present,the space utilization under China’s urban viaducts is still dominated by greening or parking,and there are problems of single utilization,insufficient space vitality and low utilization rate.The space under the viaduct of foreign cities is richly utilized,in addition to the use of greening,municipal and public facilities,there are also commercial,educational,residential buildings involved in the use.Therefore,on the basis of summarizing and analyzing the space utilization cases under viaducts in foreign countries,this paper discusses the feasibility and value of space utilization under urban viaducts from the perspective of architectural intervention,and expounds the intervention schemes suitable for viaducts from the aspects of plane,space and technical measures according to different types of architectural intervention.Finally,the space under the representative viaduct in Changchun was selected for field investigation and analysis,and the scheme design of the space utilization under the bridge was completed from the perspective of architectural intervention,in order to provide some reference significance for the use of domestic urban viaducts in the future. |
