Abstract
Larger scale dynamic centrifuge modeling has been used to examine the behavior of a soilpile-structure system during earthquake-induced liquefaction. The model consisting of a 3 x 3-pile supported structure and a saturated sand deposit was constructed in a laminar container with the inside dimensions of 74-cm length, 50-cm height and 34-cm width. Test results show that liquefaction occurred only within a finite zone in the saturated sand deposit subjected to a strong input shaking that corresponds to a maximum earthquake acceleration of 0.3 g induced probably in actual ground, which agrees well with the results of earthquake damage investigation; moreover, larger induced bending strains of foundation piles were concentrated near the interface between liquefied and non-liquefied soil layers. This concentration of bending strain may be attributed to remarkable reduction in shear resistance of liquefied soil layer relat1ve to that of non-l1quef1ed so1l layer.
