| 摘 要： | 为研究集中排烟模式下公路隧道入口段发生火灾时的合理诱导风速,以某公路隧道为背景,运用火灾动力学模拟软件FDS对隧道人口段火灾时不同坡度、不同诱导风速的16组火灾工况进行模拟研究,通过对各工况下隧道内的温度场分布及烟气控制效果模拟结果的分析,得到了各工况下的合理诱导风速,研究结果可为公路隧道集中排烟系统关键设计参数提供参考. |
| 关 键 词： | 隧道火灾 集中排烟 诱导风速 烟气蔓延 排烟效率 |

| Abstract: | To study the reasonable induced velocity of highway tunnel entrance fire in centralized smoke exhaust mode,using a certain highway tunnel as background,16 groups of fires conditions of different slope and induced velocity within the entrance section of tunnel are simulated with software of the Fire Dynamics Simulation(FDS).Based on the analysis of simulation results of the temperature distribution and effect of smoke control in tunnel under respective fire conditions,the reasonable induced velocity of fire conditions are worked out,which would provide reference for key design parameters of centralized smoke exhaust system in highway tunnel. |
| Keywords: | tunnel fire central smoke exhaust induced velocity smoke velocity exhaust efficiency |
