To evaluate the undrained behaviour of bucket foundations installed on Yoldia clay, 100 tests on bucket foundations subject to vertical and moment loadings were conducted at Aalborg university geotechnical centre. Bucket foundations are tubular steel foundations that are installed by sealing the top and applying suction inside the bucket. The hydrostatic pressure difference and the deadweight cause the bucket to penetrate the soil. In the present study, results of an experimental study addressing the effect of embedment (skirt length to the diameter) on the undrained bearing capacity of bucket foundations under vertical loading are reported. The field tests have been accompanied by the finite element numerical simulations in order to provide better understanding of influential parameters on the behavior of bucket foundations.
