Research On The Rationality Of Sunken Space Based On Urban Three-dimensionalization

With the increasingly scarce land resources and substantial growth of the urbanpopulation, layout issue has become an important conflict limiting the city’s style.Therefore, three-dimensional design has become one of the main development directions inurban design with high-rise buildings, underground tunnels and so on becoming much morecommon in the people’s lives. Sunken space, as an important transitional connection space,reasonably solve transition between the above surface and underground urban space thatmake the sunken space an integral part of the modern new space for traffic distribution andpublic events and attracts more designers’ attention. This issue researches into urbandevelopment of three-dimensional from the perspective of the sunken space and selectedsunken spaces in Beijing as the research objects. Through field research, surveys, casestudies and other methods, the reasonableness of its sinking and sinking of the conditionsare analyzed and summarized. Optimization strategies for time and space reuse in Beijing’spresent design are proposed to improve the level activity and satisfaction for sunken space.In addition, this paper, explore possible sunken space trends and innovative forms from theperspective of urban development in the future. I hope the study in this issue couldcomplement to appropriate urban development and design system.
