Abstract
In the Tohoku-Pacific Ocean Earthquake, many onshore structures were destroyed by the tsunami, the wave height of which exceeded the conventional assumption. In the future, the reinforcement of tsunami disaster prevention measures w 3 be needed, and the evaluation of inundation height and tsunami wave force on onshore structures w 3 be very important. In this study, a three-dimensional simulation that was developed by the authors and can reproduce the topography, building structures, the water depth was applied t0 Tohoku Electric Power Haramachi thermal power station which suffered serious d"11age by tsunami caused by Tohoku-Pacific ocean earthquake. The run-up process of ts 3 lami, inundation height of the main building was evaluated by comparison with the actual traces of the disaster, and the applicability of the three-dimensional simulation is examined for the evaluation of inundation height on onshore structures.
