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.
