 note = {In this study, we attempted to measure frost heave pressure, i.e., the pressure that develops in the heat-flow direction when rocks are subject to frost heave and ice lenses grow. <BR>We used two kinds of rock samples: one was Ohya tuff, whose frost heave was already known to be high, and the other was Kimachi sandstone, whose frost heave was lower than that of the former. <BR>Ohya tuff and Kimachi sandstone, in which the occurrence of frost heave has previously been confirmed, were used as specimens.<BR>To conduct the experiment, we made original frost heave experiment equipment that was combined with a reaction frame and a load cell.<BR>The test results clearly showed that the maximum frost heave pressure did not depend on the kind of rock and was proportional to the temperature gradient. <BR>In addition, we clarified that the speed of the increase in pressure was proportional to the frost heave rate ? the growth rate of the ice lens.},
