摘 要:为进一步优化高铁站设施的人性化设计,以便为乘客提供舒适满意的候车体验,众多高铁站纷纷引入多功能候车座椅。多功能候车座椅内部包含大量电气元件、电缆、电线等可燃物,增加了高铁站内电气火灾的风险系数。文章以某高铁站的多功能候车座椅为例,研究了高铁站多功能候车座椅电气火灾的发展过程。模拟结果显示,多功能候车座椅大约在火灾发生后115 s 进入充分燃烧阶段,此时热释放速率约为 156.02 kW,火灾增长类型介于中速火与快速火之间,火灾增长速率 α=0.011 820 8 kW/s2。

Abstract:In order to further optimize the user friendly design of high-speed railway station facilities,so as to provide passengers with a comfortable and satisfactory waiting experience,many high-speed railway stations have introduced multifunctional waiting seats. The interior of the multifunctional waiting seat contains a large number of combustible materials such as electrical components,cables and wires,which increases the risk coefficient of electrical fire in the high-speed railway station. Taking the multifunctional waiting seat of a high-speed railway station as an example,this paper studies the development process of electrical fire of multifunctional waiting seat in high-speed railway station. The simulation results show that the multifunctional waiting seat begins the full combustion stage about 115 s after the fire,and its heat release rate is about 156.02 kW. The type of fire growth is between medium-speed fire and rapid fire,and the fire growth rate α=0.011 820 8 kW/s2 .
Keywords:waiting seat;electrical fire;numerical simulation;heat release rate
