抜粋

When tsunami enters a water channel of an industrial facility, the water surface inside the channel rises and uplift pressures act on the ceiling if it is reached by the water surface. In this study, magnitudes and characteristics of this uplift pressure are investigated both experimentally and numerically. The results show that (1) the uplift pressure comprises an initial impulsive pressure and a following more slowly varying pressure; (2) trapped air reduces the impulsive pressure, and thus attaching a vertical barrier to the ceiling could act as a countermeasure; and (3) the impulsive pressure can be evaluated approximately with conventional predictive methods and by appropriate numerical simulations.
