Study On Integration Strategy Of Underground Space Pedestrian Traffic System In The Central District Of Chongqing

With the rapid development of Chongqing's urban economy,the continuous progress of urbanization and the environmental constraints such as topography and geomorphology,the urban space in Chongqing,especially in the central district,is seriously short of space resources.The intensive development of the city makes the urban space in the central district of Chongqing begin to expand vertically,and the large-scale development and use of underground space becomes inevitable.However,as far as the present situation of underground space development and utilization is concerned,the phenomenon of separate administration of underground space is prominent,and the degree of integration and networking is not high,resulting in a great waste of underground space resources.This thesis hopes to take the underground space pedestrian traffic system as the research breakthrough point,through the thorough research to its own characteristic and the mountain city three-dimensional characteristic,and unifies the actual case investigation and the analysis.Then,to study the integration strategy of underground space pedestrian traffic system in the central district of Chongqing,in order to promote the interconnection of underground space and the integration of ground space through the integration of pedestrian traffic system.Finally,the efficient utilization of underground space resources and the integration and symbiosis of aboveground underground space will be implemented and the further development of urban center area will be promoted.Apart from the introduction and conclusion,the paper is divided into three parts: theoretical platform,case investigation and analysis,and strategic approach to carry out the strategy research.The construction of the theoretical platform is focused on the second chapter.Firstly,the concept,method and category of integration are discussed,and the advantages of integration and the future development trend of underground space pedestrian transportation system in the central area are also put forward.Then the paper analyzes the characteristics of the underground space and pedestrian transportation system in the central area of mountainous city and analyzes the particularity of the development,and excavates the integration strategy method.Case investigation and analysis is the third chapter.Firstly,the development history and present situation of underground space and transportation system in the central district of Chongqing are summarized.Then,through the construction of the investigation system,the contents of the investigation are determined at three levels,and the investigation is carried out separately.Finally,the survey results are summarized and the strategy is preliminarily constructed.The discussion of strategy method is composed of the fourth,fifth and sixth chapters.The strategies are discussed in detail from the aspects of "use efficiency","material space" and "subject cognition".The strategy of "use efficiency" is to put forward suggestions and requirements of integrating and optimizing layout pattern from two aspects of function and streamline.The strategy of "material space" focuses on the space itself,and puts forward the ways and methods of integration from four aspects: spatial form,scale of scale,interface and spatial correlation.The strategy of starting from "subject cognition" is to change peopleundefineds negative cognition of underground space walking transportation system,and from space environment,barrier-free facilities,marking and guiding system,the goal is to change peopleundefineds negative cognition of underground space walking transportation system,and the goal is to change peopleundefineds negative cognition of underground space walking transportation system.This paper discusses the integration and optimization method of underground space walking transportation system from five aspects of natural ecological landscape and place spirit.The research in this paper is of great significance for the integration of ground and underground space and pedestrian traffic system in the urban center,and provides the perspective of thinking from the perspective of mountain cities.It provides a theoretical framework and method reference for the integration and development of underground space in urban center area,and also broadens the scope of research on underground space.
