Study on the Effect of Platform Screen Door of Different Types on Smoke Control of Platform Fire at a Subway Station
The effect of the platform screen door of different types on smoke control of platform fire at a subway station was investigated by numerical simulations. The results show that for ventilation mode only with over tunnel exhaust system activated, the efficiency of the smoke control system is the worst for fire scenario with full-seal platform screen door. In terms of ventilation mode only with the platform exhaust system, there is no obvious difference in the efficiency of the smoke control system for four kinds of the platform screen door, which is the same when the over tunnel exhaust system, the platform exhaust system and the lobby supply system are all activated. However, when the over tunnel exhaust system, the platform exhaust system and the lobby supply system are all activated and doors are closed, the efficiency of the smoke control system will decrease for fire scenario with full-seal platform screen door. This study might provide some referable information for the design of emergency smoke control of platform fire for various kinds of PSD installed.
