TSUNAMI DAMAGE ASSESSMENT ON ROAD STRUCTURES IN THE 2011 OFF THE PACIFIC COAST OF TOHOKU EARTHQUAKE
Abstract
Damage on road structures due to 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 two damage ratios RLr, RNb as the value of number of road damage points devided by total road length[km] and that of number of bridge damage points devided by total number of bridges subjected to the tsunami. Maximum value of RLr is 2.12[point/km] at Otanigawa Ishinomaki City, Miyagi Prefecture and Yagawahama Ishinomaki City, Miyagi Prefecture, and that of RNb is 1.0 at Minami-sanriku Town, Miyagi Prefecture(Utatsu Long-bridge).
