摘　　要：在分析总结现有疏散模型的基础上,基于元胞自动机原理,利用场强理论描述疏散影响因素,建立了地铁车站人员应急疏散模型,研究了疏散人员的路径选择问题及多人争夺同一格点的冲突问题。该模型不仅考虑了疏散人员的生理、心理特性而且探讨了车站的环境及引导水平对人员疏散的影响,使模型更具真实性;最后利用Visual C++进行疏散过程的仿真,模拟了地铁疏散的动态过程。On the analysis of various evacuation models, this paper established a subway station evacuation model under emer- gency conditions based on cellular automata theory and field intensity theory, analyzed the problem of evacuees path selection and competition conflict the same grid point. The model considered not only the evacuees＇ physiological, and psychological characteristics, but also discussed the influence of station environment and guide level on evacuation, which make model more authenticity. At last Visual C ＋ ＋ had been used to the simulation, which reflected the dynamic process of evacuation. The result shows the model can describe the real evacuation process.
