摘要
为了有效解决地铁隧道火灾时烟雾分布对人员疏散的影响问题,以西安地铁2号线为研究对象,针对火灾列车停留在隧道中的火灾工况,重点研究不同规模火灾条件下隧道温度、烟雾蔓延范围、可见度等参数的分布情况及变化规律。根据该隧道特定的内部几何构造,建立FDS仿真模型。利用该软件对隧道开展数值模拟研究,获得了隧道火灾发展及烟气蔓延的一般性规律。
To effectively solve the problem of smoke distribution, which would influence the passengers＇ safe evacuation during the fire in subway tunnel. The research object is the Subway Line Two in Xi＇an. According to hypothesis condition in the emergency when the burned subway train stops in the middle of the tunnel, it focuses on the study of distribution and vari ation of temperature, smoke spreading scope, visibility and other parameters under different scalesr fire. According to specific internal geometry o{ the tunnel, the FDS （Fire Dynamics Simulator） simulation model of the tunnel is built. Using the software to execute the numerical simulation study, the general rules of the fire development and the smoke spread rules in the tunnels can be obtained.
