Abstract
Seismic impacts on the engineered barrier system of the geological disposal were examined by means of the three-dimensional elastic-plastic seismic response analysis based on effective stress method. In this study, it was evaluated against the largest ground motions recorded in Japan. The numerical analysis results showed that the engineered barrier system and the surrounding bedrock were shaken together and it had sufficient robustness for the failure state. Thus we confirmed the low possibility of a reduction in the mechanical stability of the engineered barrier system due to the ground motion.
