The results of the study of the characteristics of seasonally frozen soils, insulated with urea foam

Ukhta State Technical University, Ukhta

The possibility of protecting soils from seasonal freezing, to reduce their strength during construction and remediation of oil and gas fields development sites, is considered. The results of the study of the temperature and strength of the soil in the range of regional depths of seasonal freezing from 100 mm to 1200 mm are presented, graphs of the temperature of the soil in this depth range depending on the ambient temperature and the period of soil freezing are obtained. The minimum acceptable thickness of carbamide foam is justified.
