Abstract: In order to make a reasonable and effective fire separation plan for the 1.2 × 104 m2 station hall fire compartment of an underground transfer station of intercity railway, fire risk of the hall was identified by the method of preliminary hazard analysis. Three different suggestions of using fire shutter, smoke curtain and firebarrier belt were proposed based on fire performance of the station.Advantages and disadvantages were summarized by analyzing compliances, safety evacuation, fire and smoke control of these fire separation schemes qualitatively. FDS and Pathfinder were used to build fire smoke and evacuation models to verify the fire safety of each scheme. The results showed that the three fire separation schemes can all meet the requirements of safe evacuation.

Key words: intercity railway, underground station, fire compartment, fire-barrier belt
