摘要
本文采用热针法测定了四种砂土的热导率，实验中考虑砂土孔隙率和饱和度两参数对砂土热导率的影响。文中归纳出计算砂土热导率的经验公式，并与有关文献成果进行了对比分析。
Thermal conductivity of four kinds of sands are measured by thermal needle method. effectsof porosity and degree of saturation on the therml conductivity of the sands are considered as para-meters.Empirical equation of thermal conductivity of the sands as function of porosity and degree ofsaturation is proposed.Comparison and analysis of the empirical equation with the results in some liter-ature are given.
