On the need for laboratory measurements of thermalphysic properties of permafrost soil

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

Key words: permafrost soil, coefficient of heat conduction, heat capacity, direct measurements, thermal characteristic soil.

The coefficients of heat conduction and heat capacity of the permafrost soil are significant depend on factors such as humidity, density, structure and genesis of the soil and etc. There is an indication in the Set of Rules 11-105-97 that the design of constructions I and II levels of responsibility which include the vast majority of oil and gas industry facilities, it is necessary to define the strength, deformation and thermal properties of the soil. The comparison of the thermalphysic properties of permafrost soils, defined by Building Norms and Regulation 2.02.04-88 and by direct laboratory measurements is presented in the paper.
