Título del libro: Geotechnical Engineering In The Xxi Century: Lessons Learned And Future Challenges Título del capítulo: Thermal Properties of Mexico Basin Soils
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.
