为了避免地铁站突发状况下人员疏散过程中造成人员伤亡，缩短站内人员疏散时间，以沈阳市某地铁站为背景进行物理建模，据不同的人员结构，运用Pathfinder仿真软件仿真模拟地铁站内不同人流量水平下的人员疏散，并优化了高人流量时的疏散方案。结果表明：1）确定地铁站内人流量水平在客流平峰期、高峰期均符合6 min内完成站台层全部人员疏散的要求；2）在不同条件客流高峰工况下的疏散过程中，楼梯口、闸机口出现了瓶颈，此处人员数量饱和出现了严重的排队拥堵情况，大部分人在疏散过程中遵循大多数人的意愿进行逃生；3）优化过程有效缓解了各疏散设施不均匀的问题，大大缩短了疏散时长。

In order to avoid casualties and shorten the evacuation time in the subway station in an emergency, taken a subway station in Shenyang as the background to carry out physical modeling, and simulates the evacuation of people in the subway station under different traffic levels by using Pathfinder simulation software based on different personnel structures. The evacuation plan is optimized when there is high passenger flow. The results show that: 1) It is necessary to ensure that the passenger flow level in the subway station meets the requirement of evacuating all the people on the platform floor within 6 minutes during the flat peak passenger flow period and peak passenger flow period. 2) During the evacuation process under different conditions and peak passenger flow conditions, there are bottlenecks at the stairs and gates, where the number of people is saturated and there is a serious queue congestion.Most people follow most people's wishes to escape during the evacuation process. 3) The optimization process effectively alleviates the uneven evacuation facilities and greatly shortens the evacuation time.
