Lateral Performance of Large-Capacity Helical Piles

IFCEE 2015, 2015
The lateral performance of large-capacity helical piles is of significant interest because they can offer an efficient alternative to conventional piling systems in many applications. This paper presents the results of two field lateral load tests conducted on 6.0 m and 9.0 m large-capacity helical piles installed in cohesive soil.

Lateral Resistance of Helical Piles in Oil Sands

Contemporary Topics in Deep Foundations, 2009
Although there are several methods available for estimating the axial capacities of helical piles, there is little literature available on the lateral performance of helical piles. The results of a lateral pile load test program and field monitoring of helical piles with either single or double helixes installed in oil sand soil are presented in this ...

Axial Performance of Helical Tapered Piles in Sand

Geotechnical and Geological Engineering, 2017
The axial capacity of novel spun-cast ductile iron (SCDI) tapered pile fitted with a lower helical plate is investigated. Seven instrumented piles, five SCDI tapered and two steel straight shafts, were installed in sand soil using mechanical torque. The piles were tested under axial compressive loading and their ultimate capacities were determined.

Osterberg Cell Load Testing on Helical Piles

Geo-Frontiers 2011, 2011
Helical piles are structural, deep foundation elements used as a means to transfer the applied axial and horizontal loads, and overturning moments from the superstructure to the soil substructure, within a specified criterion. The design process is complex and incorporates various degrees of uncertainties.

Helical Anchor Piles Under Lateral Loading

1984
Anchors are used in civil engineering practice to provide resistance against uplift and overturning forces for structures such as transmission line towers, aircraft mooring, pipelines, offshore structures, mobile homes, and so forth. Although there are a wide variety of anchor types available, helical screw anchors, consisting of a steel shaft to which

Pullout behaviour of model pile and helical pile anchors Subjected to lateral cyclic loading

Canadian Geotechnical Journal, 1994
This paper presents the effect of lateral cyclic loading on the pullout capacity of model and helical piles in clayey soil. The tests were conducted on short rigid model piles in the laboratory in three phases, namely lateral static load tests, lateral cyclic load tests, and vertical pullout tests.

A study of helical pile design and construction practices

2015
ABSTRACT Helical piles as a foundation solution have experienced a re-emergence in recent years in the United Kingdom, with road and rail authorities eager adopters to permit fast construction with relatively lower construction mobilisation requirements than traditional foundation solutions.
