Measuring soil thermal resistivity in a geotechnical centrifuge Available to Purchase

Migration of heat through geomaterials is of great importance to various civil and electrical engineering projects. One of the most important properties of the soil, which is necessary for estimating migration of heat through it, is its thermal resistivity. Recent studies have demonstrated usefulness of a laboratory thermal probe in evaluating thermal resistivity of glycerol and various soils compacted to different compaction states. Further, to study the influence of accelerated environment on thermal resistivity of these media, tests were conducted in a geotechnical centrifuge by modifying the laboratory setup, suitably. This technical note presents details of such a study along with details of instrumentation. It has been demonstrated that thermal resistivity of these media remains unaltered in the accelerated environment.
