摘　　要：为解决电站厂房内突发事件下安全疏散引导问题,基于对人员疏散运动规则的分析,引入吸引力概率对元胞自动机模型进行改进,建立基于扩展Moore型元胞自动机的疏散模拟模型,通过不同安全指示灯数量与位置组合条件下疏散模拟,分析不同指示灯布置方案的疏散时间。实例分析结果表明,随着指示灯数量的增加,疏散时间曲线显著降低,达到一定数量时,疏散时间曲线趋于平缓。同时在可行设计方案中,最优指示灯布设方案可使疏散效率提升1.17%~11.3%。In order to solve the problem of safe evacuation guidance in power plant, this study analyzed the layout of safety indicator using an improved evacuation simulation model. The attraction probability was introduced to improve the cellular automata model according to the evacuation rules and an evacuation simulation model was then established using extended Moore cellular automata. Through the evacuation simulation model, the evacuation time was analyzed under different number and location of safety indicator. The results showed that the evacuation time curve decreases significantly with the increase of the indicators. When the indicators reached a certain level,the evacuation time curve tended to be flat. At the same time, the optimal indicator layout scheme can improve the evacuation efficiency by 1.17% ~ 11.3% among the feasible layout scheme.
