Study On Architectural Design Of Beijing Subway Hub Station Based On Emergency Safty

Nowadays,with the continuous improvement of the national economy and the continuous development of science and technology,the process of urbanization in our country is accelerating,and the development and construction of urban rail transit has become the key construction project of each city.The increase in subway lines to expand its coverage area,the attractiveness of the passenger flow is a substantial increase.And as the intersection of urban rail transit network subway hub,often because the original design did not take into account the future direction of the development of the subway hub is not enough to adapt to the needs of today's various types of people.The characteristics of the subway station itself will often cause the peak of the flow of people,coupled with the operation of underground rail transit in which the environment and the general traffic environment is different,the environment is more closed does not open,so this internal and external conditions led to May cause a lot of emergency safety problems.In order to ensure the physical,psychological and behavioral safety of the station personnel in the sudden danger of the subway station,this paper,through the field research of the existing subway station station construction,combined with the theoretical research on the safety of the subway station,The safety of the station in the various aspects of the safety of the investigation and analysis,and affect the emergency and safety of various types of problems and risks were summarized and studied to find the cause of passenger safety hazards within the station,and from the architectural design and construction Environment and other aspects of the proposed specific transformation strategy,specifically divided into the subway hub space layout,traffic flow,construction environment and building interface and other aspects,including spatial layout and traffic flow optimization is mainly for the passenger's physical safety and The safety of the security of the building;the improvement of the construction environment and the construction interface is mainly aimed at the security of the passengers.This paper aims to provide a more systematic and reasonable guidance on the safety of existing underground hub stations in the aspects of architectural design and provide guidance and reference for building similar buildings in various cities in the future.
