摘　　要：为研究恐慌情绪下行人跨越障碍物时绊倒行为对疏散进程的影响,提出1种多模型耦合的元胞自动机模型。基于OCEAN模型和SIS模型建立个性化的情绪感染模型,模拟人群中恐慌情绪的动态感染;引入社会力模型中力的作用,判断恐慌行人是否会被障碍物绊倒;讨论情绪阈值、行人密度、可跨越障碍物长度及位置、帮扶阈值等因素对疏散结果的影响。研究结果表明:情绪阈值越高,疏散时间越长,绊倒次数越少;行人密度越高,疏散时间越长,绊倒次数越多;可跨越障碍物长度和位置的变化均会对疏散时间和绊倒次数产生一定影响;帮扶阈值越低,倒地行人的平均恢复时间越短。研究结果以期为后续此类研究和预防工作提供参考与依据。In order to study the influence of the tripping behavior of pedestrian when crossing obstacles under panic emotion on the evacuation process,a multi-model coupled cellular automata model was proposed.Based on the OCEAN model and the SIS model,a personalized emotional infection model was established to simulate the dynamic infection of panic emotion in the crowd.The role of force in the social force model was introduced to determine whether the panic pedestrian would trip over obstacles,and the influence of emotional threshold,pedestrian density,length and location of crossable obstacles,help threshold and other factors on the evacuation results was discussed.The study showed that the higher the emotional threshold,the longer the evacuation time and the lower the number of trips.The higher the pedestrian density,the longer the evacuation time and the more the number of trips.The changes in the length and location of crossable obstacles have certain impact on the evacuation time and the number of trips.And the lower the help threshold,the shorter the average recovery time of tripped pedestrian.The results are expected to provide reference and basis for subsequent such research and prevention work.
