A Comparative Study of Smoke-Ventilation System against fire in the Deeply Underground Subway Station

초록

The comparative studying of various operating for the smoke-ventilation system was performed using computational and numerical simulation for fire in the deeply underground subway station. In case of fire in the platform of deeply underground subway-station, the evacuation from fire is not easy. Because the egress route to exit is long. Therefore, the toxic gases inflows due to fire should be prevented and delayed to concourse to save passengers' life. In the paper, the reasonable smoke-ventilation system through numerical analysis was studied for preventing smoke-inflow into the evacuation way from the fire in the platform of deeply underground subway station.
