Abstract
It has been pointed out in laboratory element tests that the liquefaction properties of sandy soils are influenced by differences in specimen preparation methods. In practice, the moist-tam** method has been mostly used in laboratory tests because it allows grain size distribution and moisture content to be widely selected. In this study, a series of cyclic undrained triaxial tests was conducted under different conditions of grain size distribution and compaction thickness to reveal the effects of specimen preparation methods on liquefaction properties of two types of sandy soils. The specimens were prepared using the moist-tam** method. The number of compaction layers were either 1, 4, or 10. The results showed that the liquefaction resistance was influenced by compaction thickness, and its tendency changed depending on the grain size distribution and degree of compaction, Dc. In addition, it was found that a difference in the initial moisture content had an influence on deformation properties during cyclic loadings. In particular, the deformation properties of the specimens compacted under lower moisture content was similar to that of loose specimens. Furthermore, in the case of well-graded sand, there was no significant difference in liquefaction resistance between specimens of 10 and 4 layers; however, the liquefaction properties of a 1 layer specimen were significantly different from those of other compaction layers.
