Assessment of the thermal effect of large industrial buildings on permafrost foundation soils in Yakutsk

The results of monitoring studies of the ground thermal state beneath the Yakutsk Combined Heat and Power Plant buildings are presented in order to determine their structural stability and the possibility of further troublefree operation of the entire complex of the structures. The main causes for the formation of water-bearing taliks under and adjacent to the buildings are presented, and the factors influencing the existing geocryological situation are discussed. The continuing stable state of the buildings demonstrates the possibility of using two construction principles on permafrost at one site, including preserving permafrost and accommodating permafrost thawing.
