The so-called generalized Clausius-Clapeyron equation (GCCE),i.e., the static equation of state for "solid-liquid-porous media" systems without liquid flow through the pores, has been experimentally examined by measuring the pore liquid pressure at the solid-liquid interface, in order to verify the accuracy of our method for measuring the unfrozen pore liquid pressure. Several series of experiments were carried out using water-saturated Ohya-tuff as a porous medium specimen which was cooled from the top down. In these experiments the solid-liquid interface was always fixed on the top surface of the specimen. The experimental results imply that the measurement method should be useful for determining the relative value of the unfrozen pore liquid pressure.
