摘要
铁路隧道火灾规模是隧道火灾防治的关键问题。通过对国内外铁路隧道火灾事故及列车火灾规模大小的统计,分析了铁路隧道火灾事故发生的原因和产生的后果,提出了减少铁路隧道火灾事故的相关建议。总结了影响铁路隧道内列车火灾规模大小的因素,建议列车材质采用难燃材料、设计合理的防灾通风速度、尽可能减少列车门窗的开启数量等措施来降低隧道内列车火灾规模。在此基础上,结合我国铁路客车的特点及国外相关研究结果,建议在铁路隧道和隧道群火灾后果评估中,可采用15 MW的稳定热源作为参考。
The scale of fire accidents in railway tunnels is a key point for tunnel fire prevention.The fire accidents in railway tunnels and the results of studies on the scale of fires around the world have been reviewed and analyzed in this paper.The causes for and the result of fire accidents in railway tunnels are analyzed,and suggestions are made to reduce the fire accidents.Factors influencing the scales of fires in railway tunnels are summarized.A series of countermeasures, including employing fire-retardant materials for the trains,designing a proper disaster-prevention ventilation speed,and decreasing the number of the opening windows as far as possible,are proposed.Based on these suggestions,a 15 MW steady fire scale is recommended for the simulation and evaluation of fire accidents in railway tunnels.
