“…Many other methods for reinforcing breakwater foundation against tsunami have been developed in Japan. For example, constructing the widening work on the rubble mound (Arikawa et al 2013), installing a row of steel pile in the harbor side of the breakwater mound (Oikawa et al 2014), and putting armor units (concrete blocks) on harbor-side rubble mound (Maruyama et al 2012). However, all those techniques did not consider the earthquake induced damage of breakwater foundation such as liquefaction induced settlement and deformation of the mound.…”

Tsunami waves generated by the 2011 off the Pacific Coast of Tohoku Earthquake caused catastrophic damage to waterfront structures, such as breakwaters and sea walls. Countermeasures of compound disaster by future mega earthquake such us, Nankai megathrust earthquake and subsequent tsunami, are issues that should be resolved urgently. Therefore, the authors developed reinforcing technique of breakwater foundation using steel sheet piles and gabions that can minimize damage subjected to the tsunami higher than the design tsunami level. In this research, hydraulic model tests were performed to evaluate tsunami resistant characteristic of proposed reinforcing technique. Results of this research revealed that the settlement and the inclination of the caissons during tsunami could be significantly reduced by the proposed reinforced reinforcing technique.
