For metro stations,different station layout schemes have different evacuation capacities.How to further improve the evacuation efficiency of metro stations under the same evacuation facilities is particularly important.This paper takes a metro station in Shanghai as an example.Without changing the number and width of effective evacuation facilities,the evacuation facilities in the station are recombined to increase the number of passengers entering the station effectively,so as to optimize the layout of the station.The station model is established by BIM software,and the Pathfinder is used to simulate and analyze the personnel evacuation,and the personnel evacuation path,evacuation time,use of building escalators and the use efficiency of gate are analyzed.The results show that after increasing the effective entry of the metro station,the cumulative number of escalators on both sides of the station decreases,and the cumulative number of stairs in the middle increases,which effectively improves the conges-tion generated in the stairs in the process of passenger evacuation,and can effectively reduce the evacuation time in the station.Compared with the original scheme,the evacuation time is reduced by 15.9%.The optimized scheme im-proves the service efficiency of the stairs,and is more conducive to the evacuation of passengers in the metro station.
