Research On Design Strategy Of Connecting Space Between Upper Cover Complex And Metro Station

At present,China’s metro construction has entered a period of rapid development,and the influence of metro on urban life,urban space and urban structure has begun to be highlighted.Due to the characteristics of urban complex with diversified functions and huge scale,when it is developed and constructed with the integration of urban rail transit station with large capacity and fast speed,the articulation space between the two often reflects certain peculiarities and complexity.On the whole,the theoretical research on the interface space between superstructure complex and metro station in China is mostly at the macro planning level,but the research on the micro operation level is not perfect,and the design level lacks in-depth thinking,so the guiding role for the actual project still needs to be improved.At the level of theoretical research,although there have been systematic discussions on the design of urban architecture and public transportation interface space at home and abroad,the existing theoretical analysis and design methods still need further improvement.Therefore,this paper firstly takes the interface space between the above-mentioned complex and the subway station as the research object,and under the guidance of TOD theory,urban catalyst theory and integrated design idea,summarizes the basic combination of interface space through theoretical analysis and case study: channel type,atrium type and square type.The design principles of convenience,integration,safety and humanization of articulated spaces are proposed,and the design contents and specific implementation strategies of articulated spaces are summarized from four aspects,including articulation,flow organization,functional configuration and environmental design.On this basis,we analyzed and demonstrated the interface space of some stations of Xi’an Metro Line 4 from the perspective of designers and users by combining field research and questionnaires,combining the types of interface space combinations and influencing elements,analyzing and summarizing the current problems of the interface space from four aspects: function,flow,interface mode and environmental design,and putting forward targeted improvement suggestions and optimization plans.For example,the Xi’an University of Science and Technology Station is based on the "shared parking" model of the underground reconstruction project of Flower City Square in Zhujiang New Town,Guangzhou,and the underground parking system is used as the basis to form a "multi-functional three-dimensional" development model,which integrates the functional space of the upper buildings while establishing the underground transportation system.The underground transportation system will be established and the functional space of the upper buildings will be integrated at the same time,so as to solve the problems of inefficient access to the articulated space and difficult parking for the surrounding commercial and residential buildings.Through the study of articulated space,the article provides ideas for the integration,improvement and optimization of urban public space and transportation space,which has certain significance for the future related engineering practice and relevant research.
