According to the most unfavorable fire scenario for safety evaeuation, the AEST can be obtained through the spread of fire and smoke spread simulation. And the REST of different staff loads are calculated by empirical formula method. Through contrasting two times, whether evacuation passage setting can meet the evacuation requirements is confirmed, and then solutions are proposed. Then highway tunnel fire cause is discussed by Fault Tree Analysis method, and the effective measures to reduce the probability of tunnel fire are reducing the number of flammable materials and using fire-retardant or noncombustible materials for inner decoration are obtained.
