The design of oil and gas facilities on permafrost commonly includes several geotechnical tasks. One of them is providing operational stability of buildings and structures by project solutions based on prognostic calculations. The behavior of soils is simulated proceeding from their thermal and other physical properties. Designers and researchers most often estimate the respective parameters by calculations and use tabular data from national design standards instead of laboratory testing. We have calculated and compared several variants of input data obtained by laboratory testing and retrieved from national design standards. The results demonstrate that laboratory determination of some thermal properties of soils is indispensable for design in permafrost.
