Performance of helical piles in oil sand
TL;DR: In this paper, the results of a comprehensive pile load test program and observations from field monitoring of helical piles with either a single helix or double helixes installed in oil sand are presented.
Journal ArticleDOI
Axial compressive capacity of helical piles from field tests and numerical study
TL;DR: In this paper, the compressive capacity of helical piles in sand and clay is investigated by means of field testing and numerical modeling using the computer program ABAQUS and numerical models.

Helical piles: an innovative foundation design option for offshore wind turbines.
Byron W. Byrne,Guy T. Houlsby +1 more
TL;DR: This paper presents the use of helical pile foundations, routinely applied onshore where large tension capacities are required, for use offshore, where a significant upscaling of the technology will be needed, particularly of the equipment required for installation of the piles.
Journal ArticleDOI
Relationship between installation torque and uplift capacity of deep helical piles in sand
TL;DR: The empirical torque correlation factor (KT) as discussed by the authors, which relates the uplift capacity to the installation torque of helical piles, is routinely used as an on-site instrument for quality control with this method.
Journal ArticleDOI
Experimental Studies on Behavior of Single Pile under Combined Uplift and Lateral Loading
TL;DR: In this article, the behavior of a single pile in sand under combined uplift and lateral load was investigated using physical scaling laws, based on adopted material properties of model and prototype pile foundations.

The behaviour of anchor plates in sand
R. K. Rowe,E. H. Davis +1 more
TL;DR: In this paper, the authors describe a theoretical investigation into the behavior of anchor plates in sand, considering the effects of anchor embedment, friction angle, dilatancy, initial stress and initial stress on the anchor.

Uplift of Anchor Plates in Sand
Edward J. Murray,James D. Geddes +1 more
TL;DR: In this article, an investigation into the vertical uplift of anchor plates in a cohesionless medium is described, and factors investigated in relation to the loaddisplacement response were the size and shape of plate.

Breakout resistance of objects embedded in ocean bottom
TL;DR: For relatively shallow anchors in undisturbed dense and stiff soils, general shear along a convex, torical slip surface is observed as mentioned in this paper, which degenerates into a cylindrical surface for remolded, compressible and semiliquid soils.
