Abstract
In order to solve the influence of fire and smoke on personnel in highway tunnel for subtended traffic, analysis of measures against the fire in tunnel from structure was conducted. When the tunnel is on fire, smoke hazards lie in high temperature gas and smoke will choke people to cause deaths, fire hazards mainly lie in high temperature which will burn people to cause deaths. The separation pattern of people and smoke, and the separation pattern of people and fire are put forward. Analysis results show that unilateral closed repair road widened to 100cm is a new and feasible solution. Applying the means of setting up symmetrical emergency parking strips in the single tunnel for subtended traffic can help vehicle escape in the tunnel on fire. Setting rail car on the unilateral repair road in the single tunnel for subtended traffic can realize the separation model of people and fire. The results are significant for safety measures against fire in tunnels, and can provide reference for the subtended traffic design.
