AbstractStudies of uplift forces on steel pipe piles in frost- susceptible varved clays were carried out near Thompson, Manitoba, over three consecutive winters. The installation consisted of pipe piles, 169, 323 and 458 mm in diameter and 3.3 m long. Each pile size was replicated three times on the same site, and all piles had separate reaction frames anchored to bedrock. For the first winter, when the thick gravel layer that was placed over the site was allowed to freeze to the piles, high uplift forces were measured. The pile was isolated from the gravel in the two subsequent winters and the adfreeze values corresponded more closely to those determined previously.
