Abstract

Mountainous expressway tunnels have tiny spaces, making population evacuation difficult if a fire breaks out. Therefore, the safety risk of tunnel fire accidents must be addressed. In this paper, we comprehensively sort out the fire accident risk sources in long tunnels of mountainous expressways, establish a fire accident risk assessment model based on risk factors and guarantee factors, and calculate the fire accident risk assessment value of a long tunnel in Guizhou Province as an example. The results show that the fire accident risk assessment values in the upward and downward direction are 90.74 and 89.06, and the fire accident risk levels in the upward and downward direction are class I and class II. The risk coefficient in the downward direction is higher than that in the upward direction. The research results can improve the risk control ability of fire accidents in expressway tunnels and strengthen the risk control of expressway tunnel safety.
