摘要
根据火灾模拟程序FDS,分别建立了不同壁面边界条件的物理模型,模拟出各种模型下的隧道火灾结果,并将这些结果进行对比,其中重点分析了火灾场景中烟流温度、烟流状态等参数的不同。通过对研究结果进行分析,给出了不同的壁面条件下的简化模型比较适宜模拟的火灾场景,探讨的不同壁面条件对隧道火灾、隧道通风的影响结果能为以后的隧道火灾模拟工作提供依据,而且也可为长大隧道火灾安全工程设计提供参考。
It is simulated with FDS as real as possible in the paper. It is also compared the differences between those simplified and those not. It emphasis on the different settings of wall boundary conditions, and how the settings affect the smoke, the temperature, the heat t- ransfer between the wall and smoke, etc. It is shown that the model established in the paper with quite comprehensive parameters is inosculated with the test results very well. The achieved conclusion, how the different wall condition affects the tunnel fires and the tunnel ventilation, could be referenced by the tunnel fire simulation in future, also by the tunnel fires design for the long and large tunnels.
