Soil thermal resistivity testing
WebAug 28, 2024 · The Resistivity of the Soil. The resistivity characterizes the electrical behavior of the soil. Soils are homogeneous and isotropic when the resistivity is equal at any point and direction. Homogeneous soils are very rare. Usually, there are variations in resistivity both laterally and in-depth. WebThe dry and wet thermal resistivity of different soil samples under testing are tabulated in Table 2, when they are loaded by Q h = 728 W/m 2 at suction tension P f = ∞. The obtained results are ...
