摘要： 为了给高铁候车厅火灾安全设计（考虑行李火灾）提供参考，在某候车厅局部区域采用5 MW量热仪开展全尺寸行李火灾燃烧试验。采用50 cm×34 cm×20 cm行李箱（承装外套、裤子、短袖、内裤、袜子）、编织袋（承装被子、枕头、被褥）、双肩包（承装书本、笔记本、笔盒、笔、充电宝）等典型可燃物组成行李堆，监测记录了热释放速率、温度、辐射热流等特征参数的变化规律。结果表明：全尺度行李火灾燃烧呈现出明显的阶段性特征，其中发展阶段的温升和热释放速率增长最快，且在行李火灾的增长阶段，热释放速率的变化与t2快速火（增长系数为0.046 9）模型吻合较好。在当前场景中，行李箱、编织袋、双肩包等行李可燃物最大火灾热释放速率达到1 004 kW，最高温度接近640 oC。在当前全尺寸行李火灾中，距离燃烧行李堆1 m处的可燃物均未被引燃，但出现了软化、熔融现象。在一定程度上，1 m的间隔距离可有效避免行李明火的连续蔓延。设置9 m的隔离带可以有效起到防火隔热的作用，距离燃烧行李堆9 m位置的温升和辐射热流变化并不明显。

Abstract: In order to provide a reference for the fire safety design of the waiting hall of high-speed railway, a full-scale burning test for baggage fire was carried out in the partial area of a waiting hall with 5 MW calorimeter. Typical baggage combustible materials such as 50 cm×30 cm×20 cm hand luggages, woven bags and backpack (books, notebooks, pen cases, pens and power banks) were used to form baggage stacks. The variation trend of characteristic parameters such as heat release rate, temperature and radiant heat flow were monitored and recorded. Results show that the burning of the full-scale baggage fire presents obvious stage characteristics. The temperature rise and heat release rate increase the fastest in the development stage, and the variation trend of heat release rate in the growth stage of baggage fire is in good agreement with the t2 fast fire. The maximum heat release rate of baggage fire reaches 1 004 kW and the maximum temperature is close to 640 oC. In current full-scale baggage stack fire, the combustibles 1 m away from the burning baggage stack were not ignited, but softened and melted. To some extent, an interval distance of 1 m can effectively avoid the continuous spread of open flames in luggage stacks. The 9 m isolation belt can effectively play the role of fire and heat insulation, and the temperature rise and radiant heat flow at the location 9 m away from burning luggage stack are not obvious.
