Abstract
Geotechnical monitoring of buildings and structures in permafrost regions has become an integral part of regulatory documentation. There are clear requirements for the methodology and frequency of observations. However, with regard to geotechnical forecasting, the regulatory document adopted in 2020 provides only general requirements for predictive thermal and geotechnical calculations. Analysis of monitoring results and comparison with forecast values are left to “specialized organizations”. This paper aims to show that a geotechnical monitoring program (the document on the basis of which the work is carried out) requires more than just making a thermal field forecast and planning observation networks. It also requires developing measures for restoring geocryological conditions in case deviations occur. This allows estimating the time needed to return the temperature field to its design conditions.
