Study on the behavior of smoke from a train fire based on the track gradients in railroad tunnels equipped with a forced ventilation system

초록

This study carried out three-dimensional computerized numerical interpretation for some cases of fire outbreak in tunnels whose inner section measures 70m2 and with a 0.75 km extension. Specifically, numerical interpretation was conducted in each of the three cases of varying tunnel gradients after installing and operating a ventilation hole near the entrance and exit of the tunnel under the same conditions.
