Based on a new type of tunnel configuration model with flue in the top of it, the paper simulated the smoke pervasion when fire happens in this type of tunnel by FDS. The results show that the setting up of the flue outlet reduces the backing up distance of combustion smoke, and the distance of people fleeing is also shortened. But under this condition the smoke density inside and outside of the two flue outlet increases evidently. However, when the exhausted fans are designed at smoking outlet, the smoke movement is accelerated and almost moved into the upper space. This configuration makes the fire smoke density outside of the flue outlet reduced greatly. When the exhausted velocity increased up to a certain critical level, the smoke concentration outside of the flue outlet will reduce at the value which is no harmonious to people's life. This situation will offer a relatively safe space for people fleeing, and fire rescuing can also be carried out from two directions. Therefore, this tunnel configuration mentioned in this article give a new reference mode for personnel flee, fire rescuing and tunnel maintenance. 展开更多
