Foundation Design in Permafrost

By the end of this course, you will be able to:

• Evaluate how frozen-ground conditions and freeze-thaw processes affect foundation performance

• Plan site investigations and interpret subsurface and climate data for projects in permafrost regions

• Select suitable shallow or deep foundation systems for different permafrost conditions

• Assess bearing capacity and creep settlement for foundations constructed in frozen soils

• Account for permafrost degradation and changing ground temperatures in long-term foundation design

Description

Foundation design in permafrost requires careful consideration of ground temperature, ice content, soil behaviour, and long-term environmental change. Thawing or warming frozen soils can reduce bearing capacity, increase settlement, and alter foundation performance over the service life of a structure. If these conditions are not adequately investigated and incorporated into the design, the result may be excessive movement, structural damage, serviceability problems, or costly corrective work.

This course provides a structured approach to investigating frozen ground, evaluating its engineering behaviour, and selecting suitable foundation systems. You will learn how subsurface information and climate data inform design decisions, and how the properties of ice-poor and ice-rich soils affect shallow and deep foundations. The course also develops the analytical basis for evaluating bearing capacity and creep settlement under changing permafrost conditions.

By connecting site characterization with foundation selection and analysis, you will be better prepared to identify geotechnical risks and justify design decisions for cold-region projects. The course will help you develop foundation solutions that account for present ground conditions, anticipated temperature changes, and the long-term stability and serviceability requirements of buildings and infrastructure.
