摘要
通过对南京地区大量黏土和粉质黏土样品的比热容值和导热值的测试,分析土体热物理性质与其含水量、孔隙比的相关关系。对影响土体比热容值、导热值的因素作了详细分析,提出根据土体含水量计算土体比热容和根据含水量、孔隙比值计算土体热导率的经验计算公式。
According to the test data of the thermal capacity and thermal conductivity of large amounts of soil samples in Nanjing district, the relationship between soil thermal properties and moisture content and pore-solid ratio are analyzed. The soils used are classified as clay loam and sandy loam. At the same time, elements which have effects on the thermal capacity and thermal conductivity are analyzed. Finally, empirical formulas of thermal capacity and thermal conductivity are proposed on the basis of moisture content and pore-solid ratio.
