摘要

Fire safety in tunnels is a concern due to the large traffic flow, especially in a tunnel with a great slope. Experimental studies on the smoke spread in a small-scale titled tunnel are carried out. Effects of the titled gradients and longitudinal ventilation speed on the temperature distribution and smoke stratification downstream from the fire along the tunnel will be studied. The results show that the smoke spread upwards much faster with the slop gradient increasing, and a thick smoke layer was formed when smoke moved to the upward part of the tunnel and filled it up. The ventilation speed had a great influence on temperature distribution along the tunnel. Lower ventilation speed should be kept at the start of the fire to ensure the smoke layer not be destroyed downstream of the fire to give the tunnel users more time to escape.
