Abstract

In recent years, several cryogenic applications have involved the freezing of moist soil. Soil stabilization for excavations and construction of foundations [1] and underground storage of liquefied natural gas [2,3] are two such applications which involve cryogenic freezing of soils. In order to predict liquid requirements for freezing and maintaining the soil in the frozen state, information on the thermal conductivity of the soil is required, Practically all the work to date has been carried out in the -20° to 100°F range. The purpose of this investigation was to determine the thermal conductivity of frozen soil at liquid nitrogen temperatures as a function of the mass fraction of water in the soil. A typical sandy soil was selected as the test sample, and the guarded hot-plate method was chosen to determine the thermal conductivity.
