| Outline of Final Research Achievements |
For predicting the liquefaction-induced damage to soil-structure systems during large earthquakes with high accuracy including large deformation regime, the applicability of a large deformation analysis incorporating a strain space multiple mechanism model has been investigated. The analytical method is based on the large deformation (or finite strain) theory, in which both the material (or Lagrangian) and spatial (or Eulerian) descriptions are applied. Comparison of geotechnical centrifuge experiments with the simulation results has demonstrated that the precision accuracy of liquefaction-induced damage to soil-structure systems can be improved by considering the geometrical nonlinearity compared to numerical simulations based on the infinitesimal deformation theory.
