Adfreezing stresses on steel pipe piles, Thompson, Manitoba
Studies 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 si...
