Abstract

Many river dikes and embankments, which were damaged due to strong shaking of the 2011 off the pacific coast of Tohoku earthquake and subsequent tsunami, display diverse damage patterns depending on the topography and the types of structures. This paper analyzes the cause of damage to theYoshihama river dike located in Ofunato city of Iwate prefecture based on past field investigations and numerical simulations. Investigations revealed that the dike body had lowliquefaction resistance and the volume change after liquefaction was rather large. Two dimensional effective stress analyses showed that due to main shock and aftershock, there is a likelihood of liquefaction in dike body and the re-liquefaction possibilities are high even under small ground motion.
