Abstract
Quantification of influencing factors to liquefaction is essential for accurate prediction of in-situ liquefaction resistance. Previous studies have shown that there is a significant relationship between shear wave velocity and liquefaction resistance for a limited number of samples under the same density as in-situ with different soil fabric. However, samples such as silty sand or volcanic sand have not been investigated. In this study, reconstituted specimens were prepared using in-situ samples collected from two locations, and shear wave velocity measurements and undrained cyclic loading tests were conducted. The results show that shear wave velocity and liquefaction resistance rise with increasing over-consolidation ratio, and when they are normalized to specimens without over-consolidation history, the results are in good agreement with previous trends.
