NUMERICAL SIMULATION OF EVACUATION FROM AN INUNDATED UNDERGROUND SPACE

Abstract

Evacuation process from an inundated underground space to a ground level was investigated in this study. Numerical model which was proposed in our previous paper was applied here to simulate the evacuation behavior of people from the actual underground space in Shibuya as well as the inundation itself. Several series of computation were made, and a possible evacuation route was found for crowd of people there to go out of this space safely and efficiently without walking in the coming water. This kind of computation must be needed before we make a plan of evacuation route from such an inundated underground space in order to make a human damage be minimized.
