Then taking loess samples with different densities and moisture contents, the coefficient of thermal conductivity and specific volume heat of loess are tested. The test data show that for loess with constant water content, if the density is increased, the coefficient of thermal conductivity and specific volume heat both are increased. And for loess with constant density, if the water content is increased, the coefficient of thermal conductivity and specific volume heat both are increased too. Based on research on the test data, two formulas are obtained to determine the coefficient of thermal conductivity and specific volume heat of loess. After that it is pointed out that compared with soil density changes, water content change can result in more variations of coefficient of thermal conductivity and specific volume heat of loess.
