摘　　要：从火灾的发生,随后探测系统发现,到应急措施的控制、自动扑救,最后消防员手动扑救,从这4个方面来对地铁换乘站火灾风险做出评估体系。借鉴国外公认先进的等级划分方法,将地铁换乘站火灾划分不同等级并对不同等级进行权重分配。采用改进层次分析法建立了多层次评估指标权重模型和地铁火灾风险评价标准。结果发现:地铁车站在火灾中的逐项风险等级均达到可以接受的水平,现有车站整体风险为可接受水平。Chronological risk assessment framework was estab- lished according to the phases from fire detection system re- sponse, emergency control, automatic saving, and firefighterputting out the fire. Then, based on advanced fire classification method of other countries, subway transfer station fire was di- vided into different levels, and the weights were given. The im- proved AHP different levels were adopted to build a weight model of multi-level evaluation index and determine the evalua- tion criteria of fire risks. It was shown that the various stages of fire development level of risk score has not exceed the accept- able levels. On the whole, the risk of the existing fire station safety systems has reached an acceptable level
