摘　　要：在人员聚集的大型场所,如果紧急事件发生则极有可能造成人员的大量伤亡,因此对人员疏散行为进行深入研究,具有极大的现实意义。通过分析已有的理论基础,利用元胞自动机原理建立了人员疏散数学模型。模型采用二维元胞自动机技术,确定了元胞空间和元胞状态,建立了人员疏散行为规则并着重探讨了从众行为和建筑结构不同对疏散时间的影响。试验结果表明,该疏散仿真模型更具真实性和合理性。When accidents occur in a large building of many people, it is very likely to cause injury or death. This makes the study of evacuation dynamics very necessary. Basic principle and structure of cellular automata （CA） is analyzed, and occupant evacuation simulation model in big building is established by using CA rule. Based on math structure model, adopting the two-dimensional CA technology, the cellular space and cellular states are established, and the rule for person behavior is made. The influence of the following movement and different structures on the occupant behavior and evacuation time in several cases is mainly discussed. The results show that the evacuation simulation model is more real and reasonable.
