地铁火灾场景设计探讨

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。

Preparatory study on scenario design for subway fire

In recent years, subway fire was more and more focused in fire field. Fire design was a basic step in subway fire research, because fire scenario can affect on the study of smoke movement and safety evacuation in the subway. It was found that fire scenario design had no uniform statement in fire literatures. In this paper, the fire load and fire source location was discussed for subway fire based on the former research, and the conclusions are drawn for the further research.
