| Research Abstract |
This study proposes a method for the ventilation in expressway tunnels using negative wind-pressures generated underneath running vehicles, and aims to reduce the electric power consumption of the tunnel ventilation facility. Estimation of the air volume ventilated with this method is needed to predict the reduction of the electric power. In this study, numerical analyses for the ventilation method are performed using the vehicle-induced-pressure time history obtained from field experiments. The ventilation-duct shape is varied and a few ventilation-control methods are applied ; the optimal strategy is discussed.
