摘要: 随着我国多年冻土地区的开发和建设规模的日益扩大,在进行工程设施稳定性评价和设计计算时,要求热参数具有较宽的取值范围。过去刊行的《典型融(冻)土的热学性质》一文已不能满足需要,应及时地给予补充。尤其是需要扩大导热系数的含水(冰)量界限,以适应计算的要求。

Abstract: The purpose of this paper is to introduce the data of the thermal conductivity, determined by the comparative method, of thawed and frozen soils with high water (ice) content for engineering application.The comparative method is based on the principle of steady heat conduction with one dimension.Both the standard (its thermal conductivity is known) and the determined(the thermal conductivity is unknown) samples are put togather between two thermostats. When the temperature regime reaches stable state, the thermal conductivity of the determined sample can be obtained by measuring the temperature gradient in samples.
