Abstract: There are many layout schemes of escalator and gate in public area of metro station which can meet relevant requirements of disaster prevention and normal service functions. Due to the same evacuation facilities in each scheme, it is impossible to distinguish the advantages and disadvantages of each scheme with the current calculation method of evacuation specifications. Hence, the simulation software Pathfinder is used to simulate and analyze each scheme and their different working conditions based on three escalator layout schemes in public area of 12 m single column island platform. Meanwhile, the FDS data are imported to analyze the impact of different fire points on evacuation. From the perspective of evacuation simulation design, it can be concluded that: (1) The layout scheme of escalator + double support + elevator+ double support + escalator in the public area is more conducive to passenger evacuation; (2) Attentions should be paid to the evacuation function of vertical hinged door in paid and nonpaid areas, and the vertical hinged door should be set on the evacuation passenger flow line.
