Numerical Simulation on Smoke Control System in Cross-typed Transfer MTR Station

Subway transfer station is the intersection of the lines in the subway network structure. In this paper, the simulation model of fire simulation is established with Liuliqiao station of cross type subway station. The influence of the piston wind effect on the spread control of fire smoke at the bottom platform was studied. Through analysis, the piston wind effect strengthens the airflow disturbance in the station, and accelerates the deposition of the smoke layer, which is not conducive to the evacuation of personnel.
