Benguela-Belize Compliant Piled Tower: Installation

Offshore Technology Conference, 2006
Abstract For the Benguela-Belize Compliant Piled Tower (CPT), the interim construction phases during the installation played an important role in the structural design. Because of susceptibility to fatigue of the unfinished tower, in combination with weather sensitive installation phases, it was crucial to find the ...

Simulation of auger displacement pile installation

International Journal of Geotechnical Engineering, 2013
Auger displacement piles (ADPs) have been used throughout the piling industry worldwide for decades as foundation elements for structures and embankments. The majority of auger displacement piling is carried out in fine-grained soils, with the potential for damage to already completed piles, as well as to adjacent structures.

Numerical modeling of pile installation

2009
Pile installation leads to significant changes in the main state variables of the surrounding soil. Furthermore, the installation process may have an influence on adjacent or intersecting structures. In this paper, three-dimensional numerical analyses are presented to investigate the effect on the surrounding soil and on adjacent structures due to ...

Pile Installation in Difficult Soils

Journal of Geotechnical and Geoenvironmental Engineering, 2004
The demands on pile installation have increased dramatically in recent years in response to the threats from strong earthquakes, ice, and ship collision. Piles are being used for heavier loads and deeper penetrations in new environments and more remote areas. As a result, initial efforts at installation have frequently been unsuccessful.

Subsea Installations Using Vibratory Piling Hammers

Offshore Technology Conference, 1988
ABSTRACT During the summer of 1987 ICE hydraulic vibratory hammers were used 3 times successfully for subsea installations of anchorpiles and template foundation piles. The hammers proved to be, for the soil conditions encountered, a suitable alternative to conventionally used impact hammers.

Press-In Piling: Ground Vibration and Noise during Pile Installation

Deep Foundations 2002, 2002
Conventional dynamic piling methods are ill-suited to the urban environment. The press-in method offers an alternative technique of pile installation, which allows pre-formed piles to be installed with minimal noise and vibration. Field measurements of noise and ground vibrations during press-in piling are presented and compared to existing recommended

The effect of pile installation method on dynamic pile response

International Journal of Physical Modelling in Geotechnics, 2011
The widespread use of piled foundations in areas prone to liquefaction has led to significant research being carried out to understand their behaviour during earthquakes. A key challenge in modelling this problem in a centrifuge is the installation procedure, and in most dynamic centrifuge experiments piles are installed before the test commences ...

Vibration, Energy, and Pile Embedment Relationships during Driven Pile Installation

Foundation Analysis and Design, 2006
Installation of driven piles generate ground vibrations as the pile shears and displaces soil during its penetration. Typically, the magnitudes of ground vibrations from driven pile installations are greater as the pile penetrates stiff/dense soils than in soft/loose soils.

Effect of Pile Installation Method on Pipe Pile Behavior in Sands

Geotechnical Testing Journal, 2004
Abstract Open-ended pipe piles are often used for the foundations of both land and offshore structures because of their relatively low driving resistance. In this study, calibration chamber tests were conducted on model pipe piles installed in sands with different soil conditions in order to investigate the effects of the pile ...

Frictional Contact for Pile Installation

2007
Penetration problems in geomechanics are extremely difficult to model, because they usually involve large deformation, frictional contact and large variation of material stiffness. This paper proposes a number of strategies to deal with the computational challenges involved in modelling pile installation in geomechanics.
