| Summary | Highway bridges were damaged due to tsunami occured by the 2011 Great East Japan Earthquake. However, relationships between tsunami forces and the damaged conditions for the highway bridges are not uncertain. Moreover, estimation method of tsunami forces is one of the important problems in design of highway bridges concretely. Thus, NILIM studied on the relationships between tsunami forces acting on the highway bridges and the damaged conditions by calculating the water depth and the velocity of tsunami at the bridge sites using tsunami simulation. |
