Abstract:

The fire linkage control scheme of every system of Yangtze Rivercrossing Tunnel on Sanyang Road of Wuhan Metro is studied to guarantee the operation safety of the tunnel and metro. The subsystem of electromechanical equipment should be capable of helping administrator to make decision and carrying out effective linkage control scheme under fire rescue mode. And then the rational working modes of every system when fire occurs to rivercrossing tunnel with different times and locations are simulated, which can provide reference for diffusion control of smoke and heat, provide fresh air for personnel in tunnel, guarantee the rapid arrival of evacuation personnel, realize general disaster prevention, disaster alleviation and disaster relief, avoid secondary harm of fire, and furthest win the time and space for rescue.

Key words: highwaymetro integrated rivercrossing tunnel, metro fire, linkage control
