NUMERICAL ANALYSIS FOR EVACUATION POSSIBILITY FROM SMALL UNDERGROUND SPACE IN URBAN FLOOD
This study aims to precisely predict the inundation process occurring in small underground spaces including staircases by means of a numerical simulation. A three dimensional numerical simulation model with the volume of fluid (VOF) method is applied to a staircase and a small underground space under an urban flood condition. The simulated staircase is a full-sized hydraulic model, and the small underground space is a hydraulic model at a 1/15 scale. It is found that the numerical simulation model can be applied to the staircase during urban floods, and the computation result involving the small underground space is in good agreement with the experimental result. Furthermore, we examine the evacuation possibility from an underground space by comparing the computed water depths with the indexes. As a result, we can obtain a lot of information about the evacuation possibility from the studied underground space.
