城市水底隧道人员疏散方式的比较

研究目的：随着城市水底隧道工程的大量涌现，城市隧道防火灾是当前城市隧道设计和运营管理中的一个重要问题，对其消防对策的探索已经成为一个非常有价值的重要课题。由于城市水底隧道车流、人流复杂，深度深，呈现中间低、两头高的u型几何特点，发生火灾时烟气向两端蔓延，人员、车辆疏散困难，因此有必要对城市水底隧道的人员疏散方式进行研究。 研究结论：目前城市水底隧道常用的疏散方式为双孔隧道横向联络通道疏散，水平辅助隧道疏散和内部纵向通道疏散。通过对3种疏散方式技术经济性分析比较，得出城市水底隧道的人员疏散方式应根据具体的地质和施工条件，采用不同的疏散方式和不同的疏散通道问距。

The Comparison of Evacuation Methods in City Underwater Tunnel

Research purposes:As there are more and more urban underwater tunnel being constructed,fire safety in these tunnels becomes a big issue during the design and management,and it is very important to explore how to deal with the tunnel fire.In the urban underwater tunnel,the vehicle and people flow is huge and the tunnel is U-type,so it is difficult for people to egress when a fire breaks out. Research conclusions: Generally,there are three types of evacuation in the tunnel,which are the corridor neighbour tun...
