【 摘 要 】

For overall consideration the fire safety in subway system, the risk of train fire in the metro tunnel should be analysed and evaluated. Through theoretical numerical simulation technology in CFD, the smoke propagation characteristics of train fire with metro tunnel are investigated. The suggestion of emergency velocity would be given by considering the fire risk assessment. The result can provide technical support and a scientific basis for designing, making emergency ventilation strategies and setting personnel evacuation plans by design offices or operation managements.
