| Research Abstract |
In this study, it was shown that the thermal diffusivity of frozen-state wet rock (water-saturated rock) using an optional heating method. Then, using the method, relationships between freezing of pore water and the thermal diffusivity of sandstone and tuff were obtained. Finally, it was suggested that the behavior of thermal diffusivity of the sandstone in freezing process was able to estimate by assuming a particulate composite. On the other hand, it was found the tuff that cannot be simulated the thermal diffusivity by assuming the particulate composite.
