摘　　要：笔者以相似理论为依据 ,以旅客列车卧铺车厢 1∶5的模型为研究对象 ,利用燃烧风洞提供的流场模拟列车在隧道中运行的速度场 ,在车厢模型中加入等比例的火灾载荷 ,进行了旅客列车隧道火灾模拟实验。研究了不同列车运行速度、不同列车火灾载荷、不同火源位置以及旅客卧铺车厢的不同状况下旅客列车火灾特征及火灾中烟气蔓延规律 ,提出了满足火灾救援和旅客疏散的要求 。Referring to Similar Theory, a simulated fire experiment of a sleeper on a running passenger train in tunnel with 1:5 scale as the model added with equivalent proportion of fire load is conducted. The speed field of the running train is simulated and provided by the combustion in wind tunnel of the State Key Lab of Fire Science, USTC. A variety of running speeds, different fire loads on passenger train, different location of fire sources and different situation of passenger train are simulated and studied. From these different circumstances, different fire features of the passenger train and the stretching regularity of fire smoke are observed. The results provide the necessary demands for fire rescuing and passenger evacuation, and technical parameters for tunnel design.
