Structures located along the coastline, depending on the importance of the facility, it is necessary to ensure safety against tsunamis generated by a major earthquake. It is important to prevent structures from being damaged by the tsunami impact, which would make it difficult to restore the facility functions.
The tsunami load includes both inertia and drag force, but inertia force has a large effect on the impact wave pressure, and the angle of impact and the side slope of the structure can have a large reduction effect.
The authors have conducted a tsunami model experiment to confirm this reduction effect, and in this study, the experiment was reproduced and analyzed from the viewpoint of understanding the phenomenon and complementary validation. The phenomena are then discussed by comparing the results of the analysis and the experiment.
