Abstract

When a fire takes place, the escape tunnel which could prevent passengers and the crew from disasters would be most important facility among railway tunnel facilities for prevention of disaster. A shorter space between the escape tunnels is much better for safety because of short escape time. The establishment of short space escape tunnels(driftways) in the single track parallel tunnel is much easier. The establishment of long space escape tunnels(inclined shafts, vertical shafts) in the double track is much more advantageous economically. We, therefore, compared the movement time of smog originated from fire with the escape time of the crew and passengers for setting up the best space between the escape tunnels in the double track tunnel. We could calculate the best space between the escape tunnels in the double track tunnel properly by computer simulation.
