摘要
Thermal conductivity coefficient of rock and soil mass is important on the geothermic fundamental research and application. Concept, controlled factors and measuring methods of thermal conductivity coefficient were introduced. Controlled factors included stratum lithology, porosity, water content, temperature and anisotropy. Measuring methods of thermal conductivity coefficient included field test,indoor test, component types distinguishing, P-wave velocity estimation, etc. Thermal conductivity coefficient with field test data was usually calculated by linear and columnar source models. Indoor test included steady and unsteady measuring methods, which were applied in the materials with low-middle and high thermal conductivity coefficient respectively.
