摘　　要：为了探究疏散指示标志安装高度对疏散人员疏散效率和疏散行为的影响,通过站姿、走姿、正常跑姿及逃生跑姿四种状态下的纵向优势视线试验,开展疏散指示标志不同安装高度情况下的火灾疏散演习,并对参演人员进行意识倾向性与指示信息匹配情况的问卷调查。结果表明,被试者四种状态下视线更偏向于右侧;被试者各状态下纵向优势视线各不相同;被试者纵向优势视线与身高成正比;安装高度为300 mm时疏散效率最高,安装高度为1300 mm时疏散效率最低;参演人员意识倾向性较强,演习过程中潜意识里按照自己所熟悉的路线进行疏散。不同安装高度疏散指示标志对疏散效率影响的研究结果,为疏散指示标志的安装提供一定的科学依据。In order to explore the influence of the installation height of evacuation indicator on evacuation efficiency and evacuation behavior of evacuation personnel,the longitudinal dominant line of sight test was carried out in four states of standing posture,walking posture,normal running posture and escape running posture.The fire evacuation exercises under different installation height of evacuation indicator were carried out,and the questionnaire survey on the matching of consciousness tendency and indicator information was carried out.The results show that the subjects are more inclined to the right side in four states.Subjects in each state of vertical advantage line of sight is different.Participants longitudinal dominant vision is proportional to their height.When the installation height is 300 mm,the evacuation efficiency is the highest,and when the installation height is 1300 mm,the evacuation efficiency is the lowest.The participants have a strong sense of inclination,and they subconsciously evacuate according to their familiar routes exercise.The research results of the influence of different installation height on evacuation efficiency provide scientific basis for the installation of evacuation indicator.
