摘要
以青岛崂山隧道为研究对象,搭建中尺寸单洞双线隧道实验平台,研究了列车发生火灾时,不同纵向风速对烟气扩散和人员疏散的影响。实验结果表明,单洞双线隧道发生火灾时,火源上方隧道顶棚区域附近温度最高并向两侧呈递减分布;垂直方向,火源两侧的烟气温度从上至下呈递减分布;在隧道发生火灾时能实现列车人员安全疏散的临界纵向风速为3 m/s。
Taking Qingdao Laoshan Tunnel as the research object,the influences of different longitudinal wind speeds on the smoke diffusion and personnel evacuation in the event of a train fire were studied by building a medium-size single-hole double-track tunnel experimental platform.The results showed that,during the fire accident in the single-hole double-track tunnel,the maximum smoke temperature located near the tunnel roof area above the fire source,and the smoke temperature decreased to the two sides;the smoke temperatures on both sides of the fire source were decreasing distribution from ceiling to floor on the vertical direction;the critical longitudinal wind speed for the personnel safe evacuation was 3 m/s during a train fire in the tunnel.
