Abstract
The recent 2011 off the Pacific coast of Tohoku Earthquake earthquake and tsunami generated huge tsunamis, and many protective facilities were destroyed. Most of the damage was caused by the tsunami overflow. On the other hand, many aftershocks occurred after the main shock and attacked the coastal facilities combined with tsunami. In order to clarify the superposition phenomenon of an earthquake and the tsunami, large haydraulic experiments were conducted. As a result, it was clarified that the hydraulic pressure acting on the caisson is basically expressed as a superposition pressure of earthquake and tsunami.
