摘要：

This paper takes the subway train head fire in the upstream section of the river-crossing tunnel as the research object. The ventilation velocity with different patterns was simulated by STESS software. Then the influence of ventilation velocity on the distribution, temperature and visibility of smoke in miming tunnel was studied by non-premixed combustion model in CFD software. And the ventilation velocity of recommended pattern was measured and verified. The results show that the opening and closing of the screen door in the direction of personnel escape has a great influence on the ventilation velocity of the tunnel. When the screen door is opened, it is recommended to open the 6 TVF fans in the running tunnel and the two stations. This can effectively inhibit the smoke return and meet standardized requirements.
