The　characteristics　of　the　flame　ceiling　jet　temperature　due　to　fire　in　subway　tunnels　was　analyzed　by　using　a　1:　8　scale　model　experiment　and　numerical　simulation　to　provide　references　for　disaster　prevention　and　mitigation.　It　was　assumed　that　the　fire　source　was　at　the　center　section　of　the　train.　Fire　heat　release　rate　was　the　equivalent　load　after　similitude　transformation.　Flame　hit　directly　on　the　ceiling　and　expanded　upstream　and　downstream　along　the　ceiling.　With　heat　radiation　effects　considered,　temperature　variation　with　time　and　space　were　obtained　for　different　levels　of　fuel　consumption.　It　was　found　that　fuel　consumption　had　little　effect　on　the　trend　of　the　time-varying　temperature　during　the　combustion　with　similar　stability　time　but　different　stability　temperature.　The　maximum　temperature　above　the　flame　was　related　to　the　height　of　the　fire　source,　at　0.18H　under　the　tunnel　ceiling　rather　than　0.01H　as　for　the　pure　gas　ceiling　jet.　Different　from　the　exponential　attenuation　for　the　pure　gas　ceiling　jet,　the　temperature　of　the　flame　ceiling　jet　near　the　train　was　linearly　attenuated　along　the　tunnel,　but　the　attenuation　rate　was　almost　identical.　Only　in　regions　where　the　flame　could　not　reach,　the　gas　temperature　was　exponentially　attenuated　with　a　large　gradient.　At　certain　height　below　the　ceiling,　the　temperature　descended　quickly　and　there　was　a　low　temperature　region　existed　for　security　evacuation.
