某酒吧特大火灾场景的数值重构

Numerical simulation on a large fire accident in a bar

基于FDS对某酒吧特大火灾事故进行数值重构研究,再现了火灾发生、发展的全过程,并与火灾现场勘查报告、现场照片比对;与此同时,详细地分析和研究了火场中典型部位的温度、CO浓度及FED指数等细节性参数的发展变化趋势,结果表明,模拟中的火灾蔓延过程、烟气填充过程、热释放速率、温度等参数与火灾现场勘查笔录和电子物证基本吻合,可与火灾调查其它证据相佐证,完善火灾调查结论,为进一步研究和改善此类场所的防火措施和灭火救援方案提供了依据。

In this paper a fire accident which ever occurred in a bar is simulated by FDS. The results show that the parameters related to the processes of fire propagation and smoke filling, including heat release rate and temperature, are consistent with the electronic evidence and fire scene investigation. This indicates that the FDS simulation can be combined with other fire in- vestigation evidences to reinforce the investigation conclusions.
