The goal of this study is to achieve a better understanding of dynamic nonlinear behaviors of soil-pile-structure interaction systems under severe ground motions and to confirm applicability of a nonlinear response analysis method. We conducted vibration tests of a pile-supported structure in a liquefiable sand deposit at a large-scale mining site. This paper shows the simulation analyses of the pile-structure responses. A beam-interaction spring model was used to simulate the three-dimensional dynamic behavior of the system. Analyses results for dynamic responses of the super-structure, pile bending moments and pile axial forces during liquefaction were good agreement with the test results. It is clarified that the analysis model can properly evaluate the responses of the pile-structure system in the liquefiable sand deposits.
