大型商业综合体人员分布特性及其对疏散的影响

Personnel distribution of large-scale commercial multifunctional building and the effect on evacuation time

以徐州某大型商业综合体作为研究对象,通过人数统计系统以及观察建筑各出口监控视频,得出建筑内滞留人数以及各类人群比例,研究建筑内人员分布特性。通过设计30个模拟场景,利用BuildingEXODUS V4.0研究人员分布特性对疏散时间的影响。调查研究表明:建筑内滞留人数在14:00-16:00以及19:00-20:00范围内出现峰值,滞留人数峰值分别为12 497、17 981、15 162、11 272、10 016人;成年男士、成年女士、老人及儿童所占比例分别为35%、39%、12%、14%。模拟结果表明:疏散人员平均每增加1 000会导致疏散时间增加30s左右;老人、儿童所占比例之和的变化会对疏散时间产生较大的影响。

This thesis chooses one large-scale commercial multi- functional building in Xuzhou as object of study, and gets the number of retention person and proportion of different groups for studying the personnel distribution through the people counting system and watching surveillance video of each exit. We design 30 simulations and use BuildingEXODUS V4. 0 to study the effect of personnel distribution on evacuation time. The investigation shows that the number of retention person will appear two peaks in 14..00--16100 and 19..00--20..00, re- spectively and the peak retention person are 12 497, 17 981, 15 162, 11 272, 10 016. The percentage of adult males, adult females, old person, children in the building are 35%, 39%, 12%, 14%, respectively. The simulations show that the evacu- ation time will add about 30 s when increasing 1 000 persons to evacuees. The change of sum percentage of old person and chil- dren have much influence on evacuation time.
