Research On The Beijing Subway Station Vulnerability Under Fire Disturbance Conditions

With the rapid development of urban rail transit, subway has become a daily means of transport, the subway station is the basic unit of urban rail transit system and the interface of passengers in and out, a lot of passengers concentrate and evacuate at the station, so the liquidity is very large, especially during the peak periods, crowd is very heavy. Once burning fire, prone to lead to major disasters, bringing people’s life and property damage. With further research in the field of safety, security of the subway station was put on the agenda, how to protect the safety of people in the subway station has become issues at stake in the field of security.Subway station unique space structure determines its difficulty and complexity management measures, Mass passenger and Fire disturbance would affect the safety operation of the subway station, the most common and most harmfulness is the sudden fire accident. Taking the current research about subway fire and vulnerability on basis, put forward the concept of the subway station vulnerability under the fire disturbance conditions, Conclusion the influence factors through the research of the subway fire accident and fire disturbance characteristics, acquire the evaluation index under fire disturbance conditions through the fuzzy Delphi method. Then constructed vulnerability evaluation model under the fire disturbance based on the grey theory, to evaluate the subway station vulnerability under the fire disturbance.This paper analyze the Huoying subway station and the Xi’erqi subway station from the space structure, mass traffic and other aspects, conclude the evaluation index of the Huoying subway station and the Xi’erqi subway station under the fire disturbance. Dividing the area of the Huoying subway station and the Xi’ erqi subway station according to the personal transportation characteristics,analyzed the exposure degree,the sensitivity degree and the adaptability degree through the method of the grey relational analysis method, To collect and analyze data through the actual investigation about the the Huoying subway station and the Xi’erqi subway station, find the weak link subway station area under the fire disturbance conditions, put forward suggestions for the weak links. In order to reduce the vulnerability of the subway station under fire disturbance in each region, improve the ability of subway station against the sudden fire, protect the safety of the people’s life and property.
