凍上量と温度分布・吸水量との関係について(第2報)

Abstract

It has been pointed out that the essential part of frost heaving is laid on the mechanism ofmoisture flow to freezing front of soil. The moisture flow depends on various controlling factorssuch as particle size, suction force, temperature gradient and surcharge. So, systematic ex-perimental research would be required to make clear the relation of these factors to heaving. Itwas reported that we found the existence of the optimum heat flux to the rate of moisture flow fromthe results of experiments with the newly constructed instrument. In this paper we discuss thedependences of unfrozen water content and heat flux to the rate of moisture flow.
