摘要
火灾下的人员安全疏散问题是大型公共建筑安全设计中的重要问题,采用基于智能体的系统仿真技术,构建了大型公共建筑中人员疏散的物理模型和数学模型,通过规则推理与数值演算相结合方法对该模型进行了计算机实现,并将其与火灾模拟进行结合,从而实现火灾发展与人员疏散过程的综合评价。该系统在北京奥运场馆的人员安全疏散分析中得到运用,取得了良好的效果。
It is an important issue that mass occupants may evacuate in safety from large public buildings under fire condition. A system simulation model in which a physics model and mathematics model were included was proposed. Based on the agent technology,a computer program was developed for simulating and analyzing the egress progress of crowd flow in large public buildings through combining rule reasoning with numerical calculation,and some crowd pedestrian flow phenomenon,such as aching,rerouting,etc,could be observed from visual illustration of the scenarios. By coupling with the fire scenario simulated by CFD technology,the computer simulation program may represent the overall and dynamic process of occupants evacuation under fire expand,and the mutual relationship between the occupants’ safety and fire hazard. Through a case that an indoor stadium for the competition venues of 2008 Beijing Olympic Games was studied,it is concluded that the model is applicable.
