介绍元胞自动机理论和STEPS软件。研究音乐厅人员疏散的设计,运用STEPS软件,分析火灾导致某安全出口失效的情况下音乐厅人员疏散过程,分析其他安全出口的利用率。模拟结果显示,安全出口利用不均衡,人员在疏散楼梯口以及个别直通室外的安全出口发生拥堵。建议增大安全出口宽度,合理分流,统筹疏散;制定完善的管理制度和维护措施。将STEPS模拟结果与Pathfinder模拟结果进行对比,模拟结果基本一致。
Introduce cellular automata theory and STEPS software. Study evacuation design of concert hall staff, use STEPS software to analyze evacuation process of concert hall staff in the event of fire failure resulting in a safety exit, and analyze the utilization rate of other safety exit. The simulation results show that the utilization of safety exit is uneven, and people are jammed in the evacuation stairs and individual safety exit through the outdoor. Suggestions to increase the safety exit width, reasonable diversion, co-ordinate evacuation; develop a sound management system and maintenance measures. The results of STEPS simulation and Pathfinder simulation are compared, the simulation results are basically the same.
