Abstract

Many of the coastal conservation facilities of the fishing port were severely damaged by the wave force of the 2011 Tohoku earthquake tsunami. We evaluated the tsunami wave force by conventional hydrostatic pressure for the sea wall of the fishing port. In addition, we considered the acting force and the acting range for the water apron of the sea wall during tsunami over flow, and presented a reasonable design of the sea wall. The tsunami wave force for the sea wall is not sufficiently examine by the seabed gradient, the position of structure and the back slope of the sea wall.
