为确保越江隧道及地铁运营安全，对各系统的联动控制方案进行研究，在火灾救援模式下，保证机电设备子系统能协助管理人员在第一时间作出决策，执行正确有效的联动控制方案。模拟地铁越江隧道在不同地点、不同工况下发生火灾时各系统合理的工作方式，为控制烟雾和热量的扩散提供依据，为隧道内人员提供一定的新风量，保证疏散人员快速到达安全地点，实现隧道总体的防灾、减灾和救灾功能，遏制地铁隧道火灾次生灾害，最大限度地为隧道救援赢得时间。

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.
