The possibilities of using the results of permafrost temperature measurements for a short-term forecast of permafrost temperature regime by the extrapolation method and assessment of the stability of the pile foundation on the basis of this forecast are considered. The soil temperature has been monitored over the entire depth of the pile foundation, including one temperature sensor located under the lower end of the pile. The processing of the results of temperature measurements has been carried out according to the outlined methodology using three computer programs, links to which on the Internet are given in this article.
Keywords: temperatures observations, permafrost soil, forecast, stability, processing technique.
