Numerical study of single helical piles and helical pile groups under compressive loading in cohesive and cohesionless soils

Bulletin of Engineering Geology and the Environment, 2021
In recent years, the use of helical piles as a deep foundation option for structures has increased dramatically because they offer definite advantages over other solutions. The present study undertook a comprehensive investigation of the axial compressive behavior of helical piles in both sandy and clayey types of soil using finite element (FE ...

Physical modelling of helical pile anchors

International Journal of Physical Modelling in Geotechnics, 2007
Helical piles design is based usually on empirical correlations between the uplift capacity and the torque resistance of the pile during installation. A simplified theoretical relationship to predict the uplift capacity of deep helical piles in sand from the installation torque was reported.

Cyclic load behavior of helical pile-to-pile cap connections subjected to uplift loads

Engineering Structures, 2021
Abstract Although significant research has been conducted on helical piles, there is a lack of research and official design guidelines on how to create resilient helical pile-to-pile cap connections, especially in tall and light structures where tensile uplift loads may govern the foundation design.

Large-diameter helical pile capacity – torque correlations [PDF]

Canadian Geotechnical Journal, 2017
Large diameter helical piles are utilized increasingly to support heavy structures. Both the magnitude of the required installation torque and the pile capacity can be directly attributed to the soil shearing resistance developed over the embedded area ...

Helical Piles as a Novel Foundation System for Offshore Piled Facilities

Abu Dhabi International Petroleum Exhibition and Conference, 2015
Abstract Driven piles are used to support the majority of offshore oil and gas structures with jacket structures supported by axially loaded piles still remaining the most common form of fixed offshore platform. Piles for conventional platforms are normally driven open-ended steel piles.

Performance of Helical Piles with Grouted Shafts

New Technological and Design Developments in Deep Foundations, 2000
A new foundation system employing in-situ grouting of helical screw piles has recently been developed. As the anchor is installed into the soil, a column of grout is "pulled down" around the anchor shaft providing an in-situ grouted shaft. This foundation system has been successfully employed at several sites with very soft soils overlying a more ...
