Foundation Design in Permafrost
After participating in this course, you will be able to:
- Understand the impact of freeze-thaw on foundation performance in cold climate
- Predict the influence of permafrost degradation on response of shallow and deep foundation systems
- Identify proper foundation type for frozen soils
- Design shallow and deep foundations on frozen soils
Permafrost, or perennially frozen ground, is the ground that remains in frozen condition for two or more consecutive years and permafrost regions extend over 24% of the terrestrial surface of the Northern Hemisphere. Both shallow and deep foundations have long been used in cold region to support structures and infrastructure situated on frozen grounds.
This course presents various design techniques that can be used for the design of shallow and pile foundations in permafrost regions. Long-term stability of these foundations is mainly governed by the settlement behaviour of frozen soils which is impacted by temperature change and global warming. Therefore, both bearing capacity and creep settlement analyses of shallow and pile foundations will be discussed for both ice-poor and ice-rich conditions.
All key concepts will be explained and emphasis will be placed on the practical application of the information provided.
- Permafrost depth and distribution
- Engineering characteristics of frozen ground
- Fundamental concepts required for foundation design in permafrost
- Site investigation for foundation projects in frozen soils, subsurface exploration, soil data, climate data
- Common foundation types used in permafrost, shallow foundations used in frozen soils
- Bearing capacity analysis for shallow foundations
- Creep settlement of foundatioons in frozen soils
- Deep foundations used in permafrost
