Abstract：
Experimentally studies the thermal conductivity of soil and different ratio mixtures of sand and soil under different water ratio and density conditions by the thermo probe method. Analyses the factors affecting heat transfer performance of soil. Deduces four experimental correlations for thermal conductivity of soil and mixture of soil and sand, which are easy for project use.
