Research On Design Strategies Of Shared Space Under The Viaduct In Changsha City

Viaducts carry the capacity of urban transportation and are an important part of the urban structure,but at the same time they also bring a lot of space under the bridge that cannot be used effectively.Although people have paid more and more attention to the space under the viaduct in recent years,and the quality of the environment under the bridge has been correspondingly improved,the space under the bridge still has problems such as single use,lack of vitality,and inability to meet the current needs of people for public space.With the rise of shared travel,shared consulting,shared education and other shared services in the information age,the concept of sharing has gradually been integrated into the development of cities.Urban public space has gradually evolved into a shared space that can meet the requirements of the next era under the influence of people’s diversified lifestyles and increasingly complex social patterns.Based on this,this article takes the space under the viaduct in Changsha City as an example,intends to introduce a shared space design method to update the design of the space under the viaduct,in order to give the space under the bridge new functions,enhance the vitality of the space under the bridge,and enhance the communication between citizens.Meet the new demands of contemporary users for public space.The thesis starts with the research subject of "shared space under viaduct",and elaborates the theoretical connotation of shared space under viaduct through the study of related concepts of space under viaduct,the definition of space under urban viaduct,and the analysis of shared space theory.Later,I sorted out the expansion mode of the space under the viaduct and understood its limitations.And through the interpretation of the shared space in the architectural example,the introduction of shared space design techniques,complement and improve the expansion mode of the space under the bridge,and summarize the sharing expansion mode suitable for the space under the viaduct;on the other hand,conduct a field survey of the space under the viaduct in Changsha City,In-depth understanding of its urban background,space status,usage habits,surrounding environment characteristics and main existing problems,and the analysis of the relationship between the use function under the bridge and the surrounding environment as the starting point to analyze the population density and personnel surrounding the space under Viaduct in Changsha Based on the analysis of urban environmental factors such as structure and surrounding building types,the space under the viaduct in Changsha City is divided into three types:high population density area,medium population density area and low population density area.Finally,on the basis of the previous research,combined with the shared expansion mode of space under the viaduct,in view of the environmental characteristics,behavior requirements and existing problems of the space under the three types of viaducts,completed the construction of the shared utilization design of the space under the viaduct in Changsha City,and proposed The specific design strategy is expected to provide a new theoretical perspective and practical application possibilities for the design of the space under the urban viaduct in the future.
