Формирование температурного поля грунтового массива определяется сезонным изменением температуры наружного воздуха и тепловым воздействием транспортируемого продукта. Методом конечных элементов проанализирована динамика изменения температурного поля грунтового массива в течение 5 лет эксплуатации трубопровода для двух типов грунтов: суглинка и песка. Выявлено, что с течением времени глубина протаивания монотонно увеличивается, в песчаном грунте процесс оттаивания происходит интенсивнее. Эксплуатация трубопровода с положительной температурой усиливает процесс осадки трубопроводной системы.</p></abstract><trans-abstract xml:lang="en"><p>This paper describes a method of estimating a thawing halo around pipeline at its thermal interaction with permafrost. Formation of a temperature field of soil mass is determined by seasonal changes of the ambient temperature and the effects of heat of a transported product. We used the finite element method to analyze the dynamics of the temperature field change of the soil mass within 5 years of the pipeline work for two types of soils – clay loam and sand. It is found that over the time the depth of thawing increases monotonically and that in sandy soil the thawing process goes faster. Operation of the pipeline with positive temperature enhances the process of ground subsidence under the pipeline system.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>трубопровод</kwd><kwd>ореол оттаивания</kwd><kwd>многолетнемерзлые грунты</kwd><kwd>температурное поле</kwd><kwd>геокриологические процессы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pipeline</kwd><kwd>halo thawing</kwd><kwd>permafrost</kwd><kwd>temperature field</kwd><kwd>permafrost processes</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Геокриология СССР.
