Abstract

In the article, a predictive calculation of buried pipeline with ice-bearing and ice-rich soils thermal interaction was carried out. To describe the thermal interaction of the pipeline with permafrost soils, the enthalpy Kronik model was chosen. Calculations are made taking into account the oil temperature along the pipeline length, the physical and mechanical characteristics, temperature of the enclosing soil, regional natural and climatic characteristics. The results of the thawing depth and thaw settlement calculating have shown that the thaw settlement value depends on the thawing halo and the soil ice-content, while the change in soil types along the pipeline must be taken into account. It is also necessary to take into account the change in soil types along the pipeline. The calculation being carried out for each pipeline site, taking into account the change in soil type and condition.
