Concerns have been raised that future intense earthquakes in Japan will cause liquefaction in Pleistocene deposits beneath critical infrastructure facilities such as nuclear power plants or highways, which have not been examined by the current liquefaction assessment. In order to assess accurately in-situ liquefaction characteristic of Pleistocene deposits, shear wave velocity, \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$V_{s}$$\end{document} was introduced to quantify the effect of cementation on liquefaction characteristics. In this study, consolidation and undrained cyclic loading was applied to lightly cemented specimens while \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$V_{s}$$\end{document} is continuously measured to verify whether strengthened soil fabric degrades or not. From the results during consolidation, although the specimens with cement addiction rate, C = 1% has a higher value of stress dependency, the ones with C = 3 and 5% have a value lower than that of the non-cemented specimens. After simple nonlinear regression was conducted, the result revealed that higher cemented specimens could become hard to deteriorate soil fabric during undrained cyclic loading, although non-cemented specimens maintained its soil fabric and lower cemented specimens declines it.
