以某大型商业综合体建筑为例,针对在人员安全疏散设计中多个重要因素进行研究,以火灾疏散仿真系统平台Building EXODUS软件模拟疏散情景,采用正交试验法研究各因素对人员疏散时间的影响程度。通过正交试验结果的分析,得到各因素对疏散时间影响程度的排序为:疏散人数>人员预动作时间>避让策略>出口宽度>出口熟悉程度>人群组成>人员移动速度,并根据分析结果提出人员安全疏散建议。
Taking a large-scale commercial complex as an example, a number of important factors in the design of personnel safety evacuation were studied. The simulation evacuation scenarios were simulated using the Fire evacuation simulation system platform Building EXODUS. The orthogonal test method was used to study the evacuation time of each factor. influence level. Through the analysis of the orthogonal test results, the ranking of the impact of each factor on the evacuation time is: evacuation number> staff pre-action time> avoidance strategy> exit width> export familiarity> crowd composition> staff movement speed, and according to the analysis results Staff safety evacuation recommendations.
