Abstract
After the 2011 off the Pacific coast of Tohoku Earthquake and Tsunami, coastal structures such as breakwaters and coastal dikes have been required to have “resiliency” against large tsunamis exceeding design level, and research has been vigorously carried out. To realize resilient structures, it is important to develop methods to predict the stability limit and deformation amount against the assumed instability factors and to develop effective countermeasures for these factors. This report reviews past studies concerning resilient breakwaters and coastal dikes focusing on the stability of the armor units.
