Reserch On The Disign Of Core Traffic Space Of The Underground High-Speed Railway Station

With the rapid development of cities,people's travel demand has increased significantly,and the construction of rail transit is also in full swing.Because of the scarcity of land resources,the traditional passenger station which needs large-scale ground space is no longer in line with the development trend of new railway passenger station,especially in the core area of the city,the construction of the ground is not practical,but the construction in the suburbs will lead to the waste of a lot of time in the process of passengers from the city center to the passenger station,especially for the pursuit of high-efficiency business passengers.The underground high-speed railway station makes full use of the underground space of the city,which not only shortens the time from the city center to the station,but also meets the commuting needs of large-scale commercial passenger flow in the core area of the city.In recent years,the construction of underground high-speed railway stations has developed rapidly in China.Because of the large scale of underground high-speed railway stations and the depth of underground development,the high degree of complex functions and the strong integration with urban rail transit,the design of their core traffic space is greatly different from that of traditional railway passenger stations.How to design the traffic space with the future development trend is an important point to study the underground high-speed railway station.Based on the study of the development of underground high-speed railway station,and the analysis of compact city theory,environmental behavior theory and fire theory of underground buildings,this paper extracts the important related research factors.Combining with the analysis of the characteristics of the core traffic space of underground high-speed railway station,this paper extracts three major factors that affect the design of the core traffic space of underground high-speed railway station: spatial organization and environmental design.The design strategy of the core traffic space of underground high-speed railway station is put forward by combining the questionnaire survey and typical case study.The first chapter of this paper is to raise questions.The second,third and fourth chapters are about analysis.This paper defines the types of underground high-speed railway stations and studies the characteristics of the core traffic space of underground high-speed railway stations,analyses the influencing factors of the core traffic space of underground high-speed railway stations,and proceeds from the questionnaire investigation and analysis and practical case analysis,analyses the practice of the design of the core traffic space of underground highspeed Railway stations,as well as the existing problems.The fifth chapter is to solve the problem.Based on the research results of the first four chapters and combined with the characteristics of underground high-speed railway station,this paper puts forward specific design strategies for the core traffic space of underground high-speed railway station,namely,space organization design strategy,space environment design strategy,important node design strategy,humanization and diversity design strategy.Finally,the main research results of this paper are summarized.
