NUMERICAL MODELING OF THE PROCESS OF DEGRADATION OF PERMAFROST SOILS OF THE BASE OF THE RAILWAY ROADBED IN THE AREA OF PASSAGE OF CONSTRUCTION EQUIPMENT
Main Article Content
Abstract
When studying freezing, permafrost and thawing soils, it is absolutely necessary to develop models of processes occurring in soils and their mathematical description as a basis. This will make it possible to perform a calculated assessment of the "thawing foundation - structure" system during the entire lifetime of the object, which will make it possible to design it correctly. The article considers a soil model that allows us to consider the process of degradation of permafrost soils of the base of the railway roadbed in the zone of passage of construction equipment.
