Abstract
Frost heaving of the ground is strongly affected by thermal properties of soil. Temperature in soil, heat flux, frost heaving rate and frost penetration rate, etc. had been measured in natural ground at Kitami Institute of Technology from Nov. 2001 to May 2002. In this study, the characteristic of temperature gradient, heat flux and thermal conduction in soil were discussed. It became clear that thermal characteristics of soil are strongly related to the latent heat accompanied with frost heaving and frost penetration.
