ƒ^ƒCƒgƒ‹i‰pjF THREE-DIMENSIONAL RESPONSES OF PILE-SUPPORTED STRUCTURE IN LIQUEFIABLE SAND DEPOSITS
´˜^i‰pjF Vibration tests of a pile-supported structure in a liquefiable sand deposit were conducted at a large-scale mining site. Ground motions from large-scale blasts were used as input motions and three-dimensional responses of pile-supported structure were obtained as well as those during real earthquakes. This paper shows simulation analyses for the responses. A beam-interaction spring model was used to simulate the dynamic behaviors 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 three-dimensional responses of the pile-structure system in the liquefiable sand deposits.
