Research on smoke control system of double storage siding of an underground railway station

Based on the fire simulation software (FDS), studies the semi transverse ventilation mode of the double storage siding by simulation. Analyses the influence of key technical parameters on smoke exhaust efficiency, such as smoke vent form and spacing and smoke exhaust volume, etc. Recommends that the semi transverse ventilation system with large vents, smoke vent spacing of 40 m and smoke exhaust volume of 45 m³/s should be adopted in the underground railway station.
