Abstract
In this study, a real-scale stairway model was constructed to analyze the evacuation safety of human life due to the change of flooded stair flow. In the experiment, the water depth and flow velocity at each stage of the stairs were measured and the specific force per unit width was calculated. Using the calculated the specific force per unit width, the evacuation safety of each steps of stairs according to the change of the flooded stair flow was presented. Finally, the depth of water measured by the experiment and the evacuation safety graph of "Ishigaki" by the specific force per unit width were combined to analyze the evacuation safety by depth. As a result, it has been found that evacuation of adult man is difficult without help at the flow depth of 0.20 m or more. And it has been found that evacuation of adult women and elderly men are difficult without help at the flow depth of 0.15 m or more. Finally, it has been found that evacuation of elderly women is difficult without help at depth of 0.13 m or more.
