| 摘 要： | 隧道火灾时如果车辆停靠间距过小,可能导致火源附近的车辆被引燃从而导致更大规模的火灾。文章对隧道火灾中车辆的受热引燃机理进行了分析,并利用火灾动力学软件FDS,以南京过江隧道为背景,对隧道内车辆间的受热引燃进行了数值模拟,得出了不同火灾场景下的车辆引燃临界距离,为控制车距、减小火灾蔓延提供了依据。

| Abstract: | Fire in road tunnel may be enlarged by igniting the vehicle near the ablaze one if the spacing between them is too short.This paper analyzes the mechanism of vehicle igniting in road tunnel and the critical distance between vehicle in Nanjing underwater tunnel by using numerical simulation.The results provides basis for decreasing the probability of fire propagation in tunnel. |

| Keywords: | tunnel fire propogation heat emission igniting critical distance numerical simulation |
