Abstract

 Damage on road structures due to the ground excitation during the 2011 off the Pacific coast of Tohoku earthquake and tsunami is assessed based on the data provided by related Regional Development Bureaus, expressway sectors and local government sectors. We define a damage ratio R as the value of number of road damage points devided by total road lengths[km]. Maximum value of R for damage on road surface and road bump is 0.0224[point/km] in the range of seismic intensity 6.0 - 6.1.
