【 摘 要 】
In this study, a special section tunnel model was established by using FDS (Fire Dynamics Simulator). In the condition of mechanical ventilation, studied the effect of the model for exhaust velocity interval and curvature, slope on the smoke flow. Finally, the longitudinal wind speed of 3m/s is determined, and the results show that the curvature and slope of the tunnel have no effect on the smoke flow.
