近年来,地铁火灾是火灾科学界研究的热点。火灾场景设计是开展地铁火灾研究的基础环节,它对地铁内的烟气运动和人员疏散有重要的影响。通过对国内外文献的调研发现,地铁火灾场景的设计并无统一明确的表述。在综合前人研究的基础上,对地铁火灾场景中需要确定的火灾荷载和起火点位置进行了初步探讨,并给出了分析结果。
In recent years, the subway fire is a hot spot in fire science research. Fire scene design is the basic link in the research of metro fire, which has an important influence on smoke movement and personnel evacuation in the subway. Through the investigation of literature both at home and abroad, it is found that there is no uniform and definite statement about the design of metro fire scene. On the basis of previous studies, the fire loads and ignition points that need to be determined in the subway fire scene are discussed preliminarily, and the analysis results are given.
