Research Progress on Smoke Control Technology for Highway Tunnel Fire

Fire is one of the biggest threats to the safe operation of highway tunnels, which will not only damage the tunnel structure, but also seriously threaten the people’s lives and property. As a key link of tunnel fire rescue, ventilation and smoke control directly affects the development trend and hazard consequences of fire. Based on the previous research results, this paper introduces the characteristics of highway tunnel fire, the methods and characteristics of ventilation and smoke exhaust, the influence of tunnel structure, and fire extinguishing methods, which has certain reference and guiding significance for the design of fire ventilation and smoke exhaust, the personnel evacuation and emergency rescue in the highway tunnel.
