Resumen:

Knowledge of soil thermal properties is essential for the design of many engineering projects such as municipal solid waste and radioactive waste disposal, oil and gas pipelines, and energy geostructures. There are many studies done on soil thermal properties around the world, however, the information about the thermal properties of Mexican soils is scarce. This paper presents the results of the thermal conductivity, volumetric heat capacity and thermal diffusivity of different soils of the Mexico Basin. Twenty-eight in situ and laboratory measurements were performed using a dual thermal needle at two different sites corresponding to the Lake and Hills Zone, respectively. The results show that the thermal properties of coarse-grained soils are within the ranges reported in the literature, whereas clayey formations present low thermal conductivities. This difference was attributed to the extremely high void ratios of the Mexico Basin clays.
