摘要
为研究单洞双线隧道火灾前期,纵向挡烟垂壁对单洞双线隧道火灾烟气的影响,应用火灾模拟软件FDS建立计算模型,并搭建试验平台对计算模型进行验证;在此基础上采用计算机模拟,分析了纵向挡烟垂壁高度对隧道内烟气及温度分布的影响。结果表明单洞双线隧道中,增加纵向挡烟垂壁,能够提高人员逃生安全保障。
In order to acquire the feasibility of vertical smoke screen used in tunnel with double tracks, this study employ the fire dynamics software （FDS） and experimental verification to study the effect of vertical smoke screen on tunnel fires. After that, FDS is adopted to study the relationship between heights of vertical smoke screen and distribution of hot gas. The results indicate that the vertical smoke screen adopted in tunnel with double tracks can be employed to increase the security.
