In this study it combined fire model experiment with numerical simulation methods to study on temperature distribution characteristics of the high-altitude tunnel fire. It took tunnel fire model experiments in the discharge tunnel of Guanjiao Tunnel (32.645 km) and established the numerical model of high-altitude tunnel fire. It verified the numerical model with experimental data and studied on temperature distribution characteristics of the high-altitude tunnel fire with the numerical model finally. It obtained: Fire power was decided by the size of the fire area which also affected temperature distribution characteristics; the difference of the temperature in the tunnel between high-altitude and low-altitude was little under the condition of the same fire power; the temperature in the high-altitude tunnel was lower under the condition of the same fire size.]]>Huang, R., L.
