【 摘 要 】

The evacuation channel of the Metro tunnel serves as a corridor for the evacuation of two Metro tunnels. The trapped people need to open two fire doors at both ends of the evacuation channel. However, the fire door is a one-way fire door, and the narrow one can only be passed by one person, which is easy to cause people to block and reduce the evacuation efficiency. Therefore, it is proposed that no fire doors should be set in the evacuation channel, the accident tunnel uses the push-pull air supply mode, and the non-accident tunnel uses the double-side air supply mode strategy for smoke control. Through experimental research, it is concluded that: This mode can effectively control the flue gas and prevent the flue gas from entering the non-accident tunnel. At the same time, the fresh air of the control system has good cooling effect.
