For the force of tsunami acting on the structure
Tokuzou HOSOYAMADA
Because our country is located in the circum-pan-Pacific earthquake belt that isPacific plate border,earthquake and tsunami that many frequent.A number of tsunami damage has been reported in coastal areas, its history dates back to 684 years.
Has also been applied to the study of wave power bridge girder caused by the tsunami run-up to the river so many bridges that spill off the coast of Sumatra since the earthquake, were subjected to coastal areas of Sri Lanka and Indonesia.However, the study focused on the correlation between the bridge and tsunami is still insufficient.
In this study, we examined whether it is possible to prevent the inundation of the tsunami, such as the extent to which by Raising the embankment of the road and coastal structures by shallow water wave calculation using the numerical model.I investigated the tsunami force acting on the structure construction by using a direct calculation of Navier-Stokes equations also.
As a result, Below the results obtained by numerical calculation result is obtained by the standard formula harbor.Tsunami wave pressure acting on a structure such as a pier must be able to evaluate the safe side by standard formula harbor was found.
