Research On Fire Safety Evacuation Capacity Evaluation Of Urban Rail Transit Station

With the rapid development of urban rail transport, people are becoming increasingly concerned about operational safety. How to effectively evacuate passengers on fire disaster has become a focus in the domain of current domestic and international public safety.This paper summarize the study of domestic and international, then analysis the station evaluation of fire safe evacuation, at the same time it propose improvement ideas. It's has important significance not only to theoretical but also in practical.Firstly, this paper analysis the fire hazards characteristics and evacuation psychology-behavior features under the spatial circumstance of urban railway station. And it summarizes the fire safe evacuation factors combined with the basic knowledge of fire safety engineering. Evaluation by analyzing the characteristics of the fire station, combined with the determination of the principles of evaluation and impact of factors determine the fire safety evacuation of the station evaluation index system, explained the meaning of each index, simulation by vissim so that can calculated the quantitative index. Building an evolution model by fuzzy network analysis method which can handle the complex relationship between indexes of fire safety evacuation Put forward ideas about how to improve the capability.Finally, Take the Beijing Subway Line 5 Chongwenmen station as an example,use the methods of this paper to evaluation, and give some improved measures.
