Abstract
The problem of sustainable economic development is acutely manifested in the Arctic regions, which is due to the vulnerability of the Arctic infrastructure to climate change and landscape transformations. The reasons for deformations of buildings and structures in the Russian Arctic are considered. The problems and prospects for the development of the permafrost monitoring network are identified as the basis for the development of technical solutions for adapting the Arctic infrastructure to climate change. The analysis of technological solutions for control and ensuring the reliability of the bearing capacity of foundations by methods of regulating the state of permafrost soils is presented, a preliminary analysis of the economic efficiency of protective measures is carried out, the cost of which is at least an order of magnitude less than the expected damage to infrastructure by the middle of the century.
