A BRIEF REVIEW OF FOUNDATION CONSTRUCTION IN THE WESTERN CANADIAN ARCTIC

Problems of design and construction of foundations in permafrost additional to those encountered in temperate regions are discussed. Consideration must be given to the temperature profile in the subsurface, its variation with time and any changes imposed on it, as well as to strength and deformation properties of the frozen soils. Design schemes for foundations in permafrost are outlined. If the foundation soil is stable when thawed, normal temperate zone foundation design may be used. If the thawed state is potentially unstable, three possibilities to be considered are: (1) preservation of the permafrost, (2) acceptance of changes in the thermal regime caused by the structure, (3) modification of the foundation conditions prior to construction. Appropriate construction procedures are outlined. Pile foundations, spread footings and highway construction are briefly discussed. (TRRL)
