Measurement of the thermal conductivity of frozen soils in the range of practically significant temperature

Authors: S.S. Primakov (TyumenNIIgiprogaz, RF, Tyumen), I.A. Zholobov (Giprotyumenneftegaz OAO, HMS Group, RF, Tyumen)

Key words: permafrost soil, thermal conductivity, laboratory measurements, thermal characteristic of permafrost soil, developing of instrument for measure thermal conductivity.

Heat engineering calculations provide a reliable and safe operation of buildings and structures on permafrost soils. The initial data for the calculations are thermalphysic properties of soils, determining the velocity of propagation, form halos thawing, etc., some of which, such as the thermal conductivity of the frozen soil poorly defined by indirectly method and require laboratory measurements. This measurement of the thermal conductivity of the frozen soil should be carried out in the actual temperature range for the given conditions of permafrost, which is associated with a number of technical problems due to the complex behavior of frozen soils at temperatures close to the beginning of freezing. In this article we propose a method and instrument for solving this task.
