Outline of Final Research Achievements

Complex waves can occur around underground structures in an earthquake, and cause localized ground motion amplification on surface. In this study, we developed methods to enable high-resolution three-dimensional analysis of ground-underground structure systems. Here, we developed an automated parallel method to generate large-scale three-dimensional finite-element models of ground-underground structure systems, and developed a finite-element solver capable of attaining high-performance on full K computer system.
