Research On The Design Strategy Of Core Shared Atrium In Central Subway Station Complex

The central subway station complex will assume an increasingly important function of urban public service in the future.At present,the integrated development of central subway station and urban complex in China is not mature in many aspects.There are still some problems,such as: inefficient connection of people stream between the subway station and the urban complex;disordered spatial pattern of comprehensive development based on subway stations;negative architectural space environment leads to poor use experience and other problems.At present,in the construction of related projects,it gradually appears that the shared atrium space is used as the core of connecting the central subway station,urban comprehensive development and urban public space.However,there is still lacks of construction experience and systematic research on the design strategy of the core shared atrium in the central subway station complex.Based on these research background,this paper describes the development process of the central subway station complex and the advantages of the core shared atrium.Through the analysis of relevant architectural theoretical research and its inspiration,the needs of users,the characteristics of the space,the design content of the core shared atrium are constructed,which mainly includes people stream organization,functional integration and environmental optimization.Then,this paper analyses the completed cases,focusing on the three aspects of the core shared atrium summarized above,in order to find out their rules and the focus points of the space design.Finally this paper summarizes the design strategies of the core shared atrium in the central subway station complex in the three aspects of people stream organization,functional integration and environmental optimization.The design strategy of people stream organization mainly includes: the efficient and orderly connection of external traffic stream,and the reasonable guidance and differentiation of internal people steam.The design strategy of functional integration mainly includes: to construct the functional format system as the basis,to integrate the three-dimensional space level as the core point,and to improve the construction and operation mechanism as the guarantee.The environmental optimization design strategy mainly includes: natural lighting optimization based on the openness of space,natural ventilation optimization adapt to the complex people stream and space,and building image shaping with both internal and external considerations.Appropriately combining space syntax simulation and space environment simulation of spatial layout pattern and space morphological scale,the design strategies of the atrium are summarized qualitatively and quantitatively.To sum up,this paper studies how to promote the central subway station complex to give full play to its urban functions through the systematic design strategies of the core shared atrium,and is hoped to give some enlightenment to the related theoretical research.
