Summary

Assessment of the thermal resistivity of soils is very important for various engineering projects. Many researchers have demonstrated that soil thermal resistivity is a property of the soil that depends on various parameters such as the type of soil, particle size distribution, and compaction characteristics and hence its estimation based on existing empirical and mathematical models is difficult. This calls for fabrication of a device that can be used for determining soil thermal resistivity directly. Efforts were made to develop a field thermal probe, which is based on the principle of the transient method and is a magnified version of the laboratory thermal probe developed by the authors. Based on the results obtained, efforts have been made to develop generalized relationships for estimating the soil thermal resistivity by knowing the dry density, moisture content and percent size fraction of the various particle sizes, and validation of the proposed generalized equations was carried out using results available in the literature.
