摘要：

Evacuation　strategies　under　different　fire　scenarios　in　a　long　urban　underground　traffic　tunnel　were　evaluated　by　numerical　methods　in　this　paper.　The　available　safety　egress　time　under　no　ventilation　condition　and　the　required　safety　egress　time　were　obtained.　The　results　show　that　the　required　safety　egress　time　in　most　scenarios　are　longer　than　the　available　safety　egress　time　except　in　the　scenarios　where　the　fire　happens　near　the　tunnel　exit　portal.　This　might　be　dangerous　for　people　who　cannot　evacuate　safely.　The　smoke　control　system　must　be　run　in　time　for　assuring　the　safety　evacuation　of　the　people　at　the　upstream　of　the　fire.　For　the　scenarios　near　the　exits　of　the　tunnel,　special　measures　should　be　taken　to　make　the　cars　at　the　downstream　of　the　fire　drive　out　instantly　as　the　smoke　ventilation　system　is　in　operation.　©　2016,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
