THERMAL MODEL FOR ROADS, AIRSTRIPS AND BUILDING FOUNDATIONS IN PERMAFROST REGIONS

A THERMAL MODEL DESCRIBING THE ONE-DIMENSIONAL HEAT CONDUCTION IN A LAYERED SYSTEM IS DEVELOPED. UP TO TEN HOMOGENEOUS LAYERS, EACH HAVING DIFFERENT THERMAL PROPERTIES, POROSITY, WATER CONTENT, AND THICKNESS, CAN BE ACCOMMODATED. A PERIODIC TEMPERATURE IS INPUT FOR THE SURFACE CONDITION. THE COMPUTED RESULTS CONSIST OF THE DEPTH OF THE THAWED REGION AS A FUNCTION OF TIME. THE LAYERED MODEL IS APPLIED TO THE DESIGN OF FOUNDATIONS FOR ROADS AND AIRSTRIPS IN PERMAFROST REGIONS. A SENSITIVITY STUDY WAS MADE TO FIND THE EFFECT ON THAW DEPTH OF VARYING PHYSICAL PROPERTIES OF THE MTERIALS USED, THE GEOMETRY OF THE CONSTRUCTION, AND THE SURFACE TEMPERATURE. THE MEANS FOR EXTENSION OF THE MODEL TO BUILDING FOUNDATIN DESIGN BY MODIFICATION OF THE SURFACE BOUNDARY CONDITIONS IS PRESENTED. /AUTHOR/
