摘　　要：为了研究仓储内行人疏散行为,文中基于能见度对行人视线的影响程度,开展了四种能见度(透光率为0%、8%、15%、100%)下的室内人群疏散实验,探讨不同能见度对行人疏散的影响。研究结果表明:疏散时间与能见度负相关,即能见度越高疏散时间越少;疏散密度与能见度正相关,即能见度越高越拥堵;视线受阻情况下,高障碍物可充当“扶手”,对行人疏散速度具有提升效果;完全不可视情况下,群体的疏散速度近似正态分布;低能见度情况下,群体的疏散速度呈左偏分布;高能见度及可视情况下,群体的疏散速度呈右偏分布。受视线受阻和从众效应的影响,行人在透光率为8%、15%、100%的三种能见度下,双出口均比单出口拥堵更严重。In order to study the evacuation behavior of pedestrians in warehouses,this paper carries out indoor crowd evacuation experiments under four types of visibility(0%,8%,15%,and 100%light transmission)based on the degree of influence of visibility on the pedestrian s line of sight,and explores the influence of different visibility on the evacuation of pedestrians.The results show that evacuation time is negatively correlated with visibility,i.e.,the higher the visibility,the lower the evacuation time;evacuation density is positively correlated with visibility,i.e.,the higher the visibility,the more congested;in the case of obstructed vision,the high obstacle can be used as a handrail,which has an enhancement effect on the evacuation speed of the pedestrians;in the case of completely invisible,the evacuation speed of the group is approximately normal distribution;the evacuation speed of the group in low visibility is approximately normal distribution.In the case of total invisibility,the evacuation speed of the group is approximately normally distributed;in the case of low visibility,the evacuation speed of the group has a left-skewed distribution;in the case of high visibility and visualization,the evacuation speed of the group has a right-skewed distribution.Due to sight obstruction and crowd effect,pedestrians are more congested at double exits than single exits in all three visibility levels of 8%,15%,and 100%light transmission.
