摘　　要：采用统计法的原理对地铁列车发生轰燃时的热释放速率大小进行计算。以锥形量热仪中测试得到的各材料热释放曲率曲线为基础,并根据各材料的表面积及用量统计结果,计算得到整个地铁车辆的热释放曲率曲线,为车辆防火设计时可燃材料的选取及布置提供依据,以及为隧道通风系统设计容量提供依据。In this paper, by using principle of statistics when flashover occurs on the subway train, intend to calculate the size of HRR（heat release rate）. This paper base on various materials heat release rate curve that test in the cone calorimeter, as well as statistical results of surface area and consumption of each material, then calculate to get the heat release curve of curvature for metro vehicles, in order to provide the basis for selecting and arranging the combustible materials when design metro vehicles fire prevention, and provide the basis for tunnel ventilation system design capacity.
