Optimization Strategy Study On The Continuity Design Of Underground Public Link Space In Urban Central Areas

In recent years,with the large-scale development and construction of underground space in my country,the underground space mainly relying on rail transit construction presents the characteristics of fast construction and wide distribution.Facing the scale impact of large underground public spaces on the urban spatial structure,the phenomenon of wasteful use of space,and the isolated development of small and medium-sized underground public spaces far away from rail transit,and the situation of imbalance with the urban public space structure,explore the use of underground public link space Continuity optimization strategy research as a response method to integrate urban space and link humanistic life.As an important part of urban public space,underground public link space is a place to link users’ daily activities and communication.The real environment of stock planning and the content of urban design have given the existing underground public link space a good opportunity for development.Along with the research and attention to the development trend of underground public space details and humanized design,an in-depth analysis and summary of the existing underground public link space Continuous optimization strategy is of great significance.On the basis of sorting out the current status of relevant research at home and abroad,the paper studies the types,elements and connotations of underground public link spaces,and clarifies the research objects and the scope of case selection.Based on the theory of urban-building integration,boundary effect theory and environmental behavior theory,continuous design optimization is the goal,and the underground public link space in the urban central area is the research object.Combined with the case study of the underground public link space in the central area of Qingdao,select Integrating the environment,space ontology and behavioral activities as the research perspective,summarizing the influencing factors of continuity design.Taking three key underground public link spaces in the central area of Qingdao as typical cases,this paper conducts an in-depth analysis of the current situation,characteristics and problems of the continuity of linear,planar,and composite underground public link spaces,and explores the continuity methods of existing underground public link spaces in Qingdao.,and then summarize and analyze the content requirements for the optimization of the continuity design of the urban underground public link space,and condense the optimization strategy for the continuity design of the underground public link space in the urban center.The continuity of the underground public link space in the city center needs to be solved through urban design methods,guided by the four continuity optimization principles of overall structure continuity,functional space compounding,traffic connection networking,and space transition humanization,and Qingdao The underground public link space in the downtown area is located in the vitality-oriented demand of the old city,the leisure and cultural needs of the seaside area,and the functional complex demand of the commercial center area.On the basis of multidimensional urban design goals,the association integration of the continuation of multiple spatial orders is proposed.,Continuing the interactive fusion of multi-element organization and the vitality aggregation strategy and its specific operation design method of continuing multi-dimensional perception participation.
