Abstract
Freeze-thawing phenomena of the ground occur due to temperature variability in the cold districts. It is important to understand mechanical characteristics of the ground subjected to freeze-thaw sequence. In order to investigate the deformation properties of volcanic coarse-grained soil in freeze-thaw process, a series of cyclic triaxial test for determining defomation properties were performed on specimens with artificially freeze-thaw cycles. The results showed that freeze-thaw sequence effects a change in deformation properties, especially G0 of volcanic coarse-grained soil. The main reason is attributed to increase of finer content and change of pore structure caused by freeze-thaw sequence.
