摘　　要：为研究城市轨道交通换乘车站发生突发事件时人员的疏散过程、疏散路径和优化方法,通过将仿真模拟方法与疏散路径优化模型相结合,构建引导人员位置优化模型与疏散路径优化模型,模拟换乘站发生突发事件时引导人员作用下的紧急疏散情况。研究结果表明:加入引导人员的疏散模型可较为真实地反映突发事件下乘客的疏散过程;设置引导人员后,总疏散时间较无引导人员时减少26.08 s;8条最优疏散路径的疏散用时均小于245.68 s。研究结果可为城市轨道交通车站开展应急疏散和应急处置工作提供参考。In order to study the passengers evacuation process,evacuation path and optimization method of urban rail transit transfer station in emergencies,the optimization models of guidance personnel position and evacuation path were constructed by combining the simulation method with the optimization model of evacuation path,and the emergency evacuation of transfer station under the role of guidance personnel in emergencies was simulated.The results show that the evacuation model adding guidance personnel can accurately reflect the evacuation process of passengers in emergencies.The total evacuation time reduces by 26.08 seconds compared to that without guidance personnel,and the evacuation efficiency increases by 9.6%after setting up guidance personnel.All the evacuation time of the 8 optimal evacuation paths are less than the total evacuation time.These research results can provide reference for emergency evacuation and response work of the urban rail transit stations.
