摘　　要：在分析中低速磁浮线路高架桥上事故特点的基础上,归纳了竖向、纵向、横向等应急疏散模式,以及既有的桥上应急设施类型。通过计算机多智能体仿真平台Pathfinder,建立了磁浮列车桥上人员疏散仿真模型,计算分析了不同工况下桥上应急设施及其设计参数对人员疏散时间的影响。研究结果表明:采用Pathfinder仿真平台可以较为真实地模拟桥上人员的疏散过程和疏散时间;竖向疏散的独立楼梯疏散效率和安全性能较高;疏散平台的平台宽度和栏杆间隔对人员纵向和横向疏散时间有一定影响。Based on the characteristic analysis of accidents on medium and low speed maglev bridges,vertical,longitudinal and horizontal evacuation modes and existing emergency facilities on bridges are summarized.Based on multi-agent simulation platform Pathfinder,the simulation models of passenger evacuation on maglev bridges are built and the influence of emergency facilities and design parameters in different cases on passenger evacuation time is calculated and analyzed.Research results show that Pathfinder can provide a realistic simulation of process and time for passenger evacuation on bridges.Independent staircases of vertical emergency evacuation modes are of higher efficiency and safety.And the width of walkways and railing interval affects passenger longitudinal and horizontal evacuation time to certain extent.
