Abstract
A large earthquake in the Kumamoto district in the south of Japan in April 2016 occurred twice within 28 h with a magnitude class 6.5. Due to this earthquake many houses and roads collapsed. In order to investigate the behavior of EPS embankments when a large-scale earthquake acts consecutively, an EPS embankment model with a scale of 1/5 was built and a shaking table experiment was conducted using the shaking table (3 m × 2 m) at the University of Tokyo. The EPS embankment was found to cause rocking phenomenon due to seismic motion. As a countermeasure, in addition to the effect of an improved Joint Metal Binder (JBM), the effect of applying a larger number of JMBs was also investigated.
