In order to study the influence of subway platform exhaust speed on personnel evacuation under different fire power, a physical model of an island subway station is established by Revit software, and the distribution and change of temperature, CO volume fraction and smoke layer height under different exhaust speed of subway station under three fire powers of 1.7 MW, 3 MW and 5 MW are simulated and analyzed by fire dynamic simulator (pyrosim). The results show that within 360 s of the specified safe evacuation, the fire power increases, the temperature at the platform escape stairs, the volume fraction of CO increases, and the height of smoke layer decreases. With the increase of fire power, the exhaust speed has a greater impact on the safe evacuation of personnel.
