Abstract
<p>This paper reports on the quality evaluation of soil samples taken by small-scale freeze sampling technique. The quality of samples from model ground was evaluated by using a pressure chamber and Vs measurement, focusing on the changes inDr and G0 at the given confining pressure. The changes in Dr and G0 were 2.7% and 4.3% for the hollow cylindrical specimen trimmed from freezing sample taken from dense model ground. Therefore, there is a high possibility that small-scale freezing sampling can be used to obtain hollow cylindrical specimens which remain the in-situ density and soil structure.</p>
