Abstract

In order to explore design rationality of landings at egress door of kindergartens and to fill in the blank of children's evacuation behavior data in this partꎬ evacuation drills on landings at egress doors in two fulltime six ̄classroom kindergartens were conducted and evacuation behavioral data at landings of 4 different designs were obtained. Thenꎬ their walking speedꎬ evacuation time and flow rate were analyzed and compared. The results show that walking speed of children aged 4-6 on non ̄smooth steps is between 0􀆰 52-0􀆰 98 m / s. Design difference of landings has obvious influence on children's evacuation behavior and evacuation effectꎬ and double ̄sided landings can increase flow rate by 1􀆰 8 times.

出口门平台设计对儿童疏散行为的影响

为探索幼儿园出口楼梯口设计的合理性，填补本部分儿童疏散行为数据的空白ꎬ对两所全日制六教室幼儿园进行了出口楼梯口疏散演练，获得了4种不同设计的楼梯口疏散行为数据。然后对ꎬ他们的行走速度ꎬ疏散时间和流量进行分析比较。结果表明:4-6岁儿童在非光滑台阶上的行走速度在0􀆰52 ~ 0􀆰98 m / s之间，着陆的设计差异对儿童的疏散行为和疏散效果有明显影响ꎬ，双面着陆可使流量提高1􀆰8倍。
