摘　　要：为降低和消除公轨合建隧道轨道层地铁火灾的危害,运用Pathfinder建立了轨道层B型地铁疏散模型,并利用实验数据修正了模型中乘客在疏散平台上的速度。针对地铁中部起火且正对疏散门的最不利火灾场景,模拟分析了疏散门设置间距和宽度对人员疏散的影响。结果表明车厢侧门的流量分布主要与疏散门间距有关,侧门的开启方式会影响乘客整体疏散时间;当疏散门间距小于地铁车身长度一半时,疏散时间同时受疏散门间距和宽度的影响;当疏散门间距大于地铁车身长度一半时,疏散时间主要受疏散门间距的影响。研究可为公轨合建隧道轨道层疏散门的设计提供技术参考依据。In order to reduce and eliminate the harm of subway fire in the road-rail tunnel,the Pathfinder is used to establish the B-type subway evacuation model in the rail layer,and the experimental data is used to modify the mov⁃ing speed of passengers in the model on the evacuation platform.The model is used to study the influence of the spacing and width of evacuation doors on personnel evacuation with the worst scenario of fire accidents,where the fire location is in the middle of the subway and facing the egress door.The results show that the flow distribution of compartment side door is mainly related to the distance between egress doors,but not to the width of egress doors,and the opening way of subway side door will affect the overall evacuation time.When the distance between egress doors is less than half the length of subway,the evacuation time is mainly affected by the distance between egress doors and the width;when the distance between egress doors is more than half the length of subway,the evacuation time is mainly affected by the distance between the egress doors.The research may provide technical reference for the design of egress door of rail layer in road-rail tunnels.
