ABSTRACT
With rapid development of tunnel construction in China, the number of road tunnels has increased sharply to serve the perpetual growth of both freight and transport for the populace. The consequence of the growth in the number of road tunnels and the volume of traffic is an increasing occurrence of severe fire incidents in tunnels. Also, as tunnel construction technology has evolved, so the feasible length and cross-section of road tunnels have expanded. Subsequently, the control of such incidents has become more difficult for the emergency services of large cross-section road tunnel.
