Underground Commercial Space Design Based On The Concept Of "Urban Renewal"

The development and utilization of underground space is increasing day by day along with the rapid rise of China’s economy,and problems such as traffic congestion,dense population,environmental pollution and ecological imbalance have arisen one after another in the process of urbanization.It is necessary to develop and utilize underground space in a rational,orderly and efficient manner and take scientific,systematic and sustainable measures in order to alleviate various contradictions in urban development and fundamentally solve "urban problems".Over recent years,the diversification of underground space and the large-scale construction of urban subways have made the underground commercial space shoulder the function of integrating the hub area and underground business,and the development and utilization of underground commercial space is also on the rise.This year is a critical year for Qingdao to promote urban renewal and urban construction offensive action.North Qingdao City District is closely focused on the "urban renewal battlefield",both inside and outside,to improve the effectiveness,and strive to write a new chapter of high-quality development.It forms the background of Taidong pedestrian commercial street area in the north district of Qingdao city,and the underground project of Weihai Road combined with plain warfare is the research object to build the first large-scale integrated human defense complex underground project near the commercial circle in Qingdao.The project realizes the combing of domestic and foreign research results and the research on Qingdao Taidong Pedestrian Street,combining the theories of "urban renewal" concept,functional layout and business pattern to analyze the problems of existing commercial space,and summarize the elements affecting the design of urban commercial space through case comparison and field research;The numerical model is constructed,and the hierarchical analysis and fuzzy evaluation are used to propose the relevant impact index elements of the underground commercial space to meet the physiological and psychological needs of people in the underground commercial space.To build the framework and provide new ideas for a diverse underground commercial shopping environment.With the content proposing design points from three aspects of urban land intensification,human behavior needs and commercial business,the content explores the use of specific architectural design techniques to create a humane underground commercial space,following the design principles of humanization,safety and health,and optimizing the design in terms of accessibility of space,architectural layout and acoustic environment.Moreover,the section of "Weihai Road combined with underground project" is used as a case study for empirical analysis and research,with a view to providing a certain reference value for the development of similar projects and guiding the planning of future underground commercial space.
