Formation of the temperature of foundation soils during usage of thermal stabilizers in the conditions of the cryolithozone of the central Yakutia
Abstract.The subject of this research is the interaction of the seasonal thermal stabilizers with the soils, processes of thermal and mass transfer and formation of cryotextures. The thermal stabilizers found broad implementation in northern construction for strengthening foundations of buildings formed with plastic and thawed dispersed soils with installation of Anti-filtration screens and ice walls. The efficiency of the work of thermal stabilizers is assessed based on the rate of formation of the calculated temperature schedule in foundations of engineering structures. The presented data of formation of temperatures of the soil foundations cooled by the liquid-vapor thermal stabilizers reflect regularities characteristic for dispersed soils of all types with various indexes of moisture and salinization for buildings with ventilated crawl spaces.
