Research On The Bridgehead Space Design Of Cross-river Bridges In The Proper City Of Chongqing

As a riverside city,Chongqing is known as the "bridge capital".In order to meet the frequent material exchange between the two sides of the Strait and people’s daily travel,the number of bridges in the main urban area of Chongqing is increasing.With the development of the city,there is an increasing shortage of land resources and people’s higher and higher requirements for the quality of the surrounding environment.As a goal that can be redeveloped in the city,the bridgehead space has become an urban public space for people through reasonable resource allocation,so as to improve the overall public space service quality of the city.Taking the bridgehead space of river crossing bridge as the research object,this thesis expounds the core concepts of relevant research and relevant theoretical basis at home and abroad from the two aspects of "bridge landscape" and "urban gray space",verifies the feasibility of the research direction,and lays the theoretical foundation of the research at the same time.After the field investigation of 33 river crossing bridges in the main urban area,the bridgehead space is divided according to different classification methods,and the research sample points are selected.After sorting out the utilization mode and form of bridgehead space according to the research results,this thesis summarizes the existing problems of bridgehead space through its current characteristics,including "spatial function" : poor spatial utilization system,lack of function and imbalance with urban system;"Visual landscape" : low landscape quality,lack of visual effect of spatial interface and aging infrastructure;The spatial form of "spatial form" is single and homogenized seriously;The management operation of "implementation management" is imperfect and the ownership is unknown;"User group" has obvious stratification of people based on time period,etc.Combined with the relevant theoretical knowledge at home and abroad,the author summarizes the research strategies of the bridgehead space design of river crossing bridges in the main urban area of Chongqing through the field investigation of the bridgehead space of river crossing bridges in the main urban area of Chongqing and the existing design case ideas and space design strategies at home and abroad:(1)connection-integration of urban system: systematize the bridgehead space according to the regional advantages and surrounding resources,and consider the bridgehead space as a part of the urban public space as a whole;(2)Compound-urban space extension: make compound use of site polysemy,establish the combination of pedestrian transportation and public transportation,break the boundary and penetrate into each other for the combination of bridgehead space interface and urban space interface;(3)Management-clear ownership responsibilities: improve relevant laws and policies on the utilization of bridgehead space,clarify space ownership issues,and build an integrated design process(4)optimization-internal landscape improvement: scene of space interface,landscape of infrastructure and combination of rain and flood management;(5)Deduction-externalization of urban context: explore the site history,inherit the urban context,improve the identity of bridgehead space,the connotation and meaning of urban context,and the interaction between people and space.For the design and practice of the surrounding environment,current problems,humanistic factors and users of the bridgehead space,the design strategy of the bridgehead space of the river crossing bridge is used to verify the feasibility and enforceability of this point of view,and try to provide reference for beautifying the city image and creating a comfortable and pleasant bridgehead space with excellent service quality.
