Internal Observation of Soil in Frost Heave Process Using the X-Ray CT Scan

Many studies have been conducted on frozen soil, and numerous models and theories on frost heaving have been published. However, microscopic observation of the internal structure of frozen soil with the conventional technology is difficult, and verification thereof has not been sufficient. Therefore, in this study, we developed a small frozen experimental apparatus that can be placed in an X-ray CT scanner. Since the X-ray CT system used in this...
