利用PHOENICS模拟了两种纵向风速下隧道内火灾烟气的发展情况,分析了人员疏散方向离火源点不同距离处烟气的温度和浓度分布。提出了利用联络通道来疏散部分人群的方法,得出了使联络通道内无烟的纵向通风速度,为提出全面的地铁区间隧道火灾人员疏散模式提供有益参考。
PHOENICS was used to simulate the development of smoke in the tunnel under two longitudinal wind speeds. The temperature and concentration distribution of flue gas at different distances from the fire source were analyzed. The method of utilizing the communication channel to evacuate some people is proposed. The longitudinal ventilation speed of smoke-free communication in the communication channel is obtained, which provides a useful reference for the comprehensive evacuation mode of fire personnel in the metro tunnel.
