TSUNAMI-SEABED-STRUCTURE INTERACTION FROM GEOTECHNICAL AND HYDRODYNAMIC PERSPECTIVES: ROLE OF OVERFLOW/SEEPAGE COUPLING

  • Shinji Sassa

Abstract

This paper presents some recent research advances in tsunami-seabed-structure interaction following the 2011 Tohoku Earthquake Tsunami, Japan. Role of overflow and seepage coupling is highlighted, based on the effect of tsunami-induced seepage on piping/boiling, erosion and bearing capacity decrease and failure of the rubble/seabed foundation (Takahashi et al., 2014; Sassa, 2014; Sassa et al., 2016).
