A study of the changes brought about in the thermal regime beneath buildings constructed over permafrost and the effect of these changes on the buildings has been made by observing eleven test buildings with various types of foundations for a period of about five years. The principal measurements included temperature readings in the foundation and soils beneath the structures and vertical movements of points on the buildings. These observations have resulted in findings concerning the permanence or degradation of permafrost, the seasonal freezing and thawing patterns, the relation of these thermal changes to seasonal and yearly vertical displacements of the buildings, and structural damage in the buildings resulting from the movements. The effect of such foundation features as air spaces beneath floors, fills of non-frost-susceptible materials, post and pad construction, concrete slab floor construction on fills, insulated and non-insulated built-up wooden floors on fills, and insulation layers in fills have been studied.
