Abstract
A series of cyclic triaxial tests was conducted to investigate liquefaction and post-liquefaction recompression characteristics of sands containing non-plastic silts as the fine which were prepared by tamping and water sedimentation at laboratory. In particular, the investigation was focused on the effects of relative density, silt content and kind of silt on those characteristics. Based on the results from tests, the emphasis was placed on the following: (1) There is a unique relationship between normalized strength ratio and number of load cycles, which is independent of the above three influential factors. (2) Post-liquefaction volumetric strain can be correlated to the liquefaction safety factor defined by the cyclic strength ratio, irrespective of the fine content.
