FE Simulation of Model Tests on Vibratory Pile Driving in Saturated Sand
Lecture Notes in Applied and Computational Mechanics, 2017The present study reports the extensive comparison of model tests with numerical simulations of vibro-driven pile installation in saturated sand. The purpose of the study is to validate existing simulation techniques and to investigate the ability of those to reproduce effects experimentally observed during pile installation. A limited number of cycles

Vibratory driving of piles and sheet piles – state of practice
Proceedings of the Institution of Civil Engineers - Geotechnical Engineering, 2021The installation of piles by vibratory methods is discussed and illustrated by case histories. The influence of vibration frequency – which can be controlled during vibratory driving but not during impact driving – on pile penetration, bearing capacity and emission of vibration is examined.

Modelling of vibratory pile driving in sand
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1992AbstractA model for vibro‐driving of rigid piles in sand is proposed incorporating the interaction of the vibrator–pile–soil system. The vibro‐driver force and the non‐linear soil resistance (dynamic f–w and q–w relationships) have been quantified in terms ofin situstress, relative density and particle size.

Numerical studies of vibratory pile driving
International Journal for Numerical and Analytical Methods in Geomechanics, 1988AbstractThe processes underlying pile installation by vibratory loading rather than impact loading are complex. However, numerical studies using simple models for soil behaviour do throw some light on the basic dynamic processes involved. As better soil models become widely used, quantitative analyses using the techniques described, or simplifications ...

The underwater sound field from vibratory pile driving
The Journal of the Acoustical Society of America, 2015Underwater noise from vibratory pile driving was observed using a vertical line array placed at range 16 m from the pile source (water depth 7.5 m), and using single hydrophones at range 417 m on one transect, and range 207 and 436 m on another transect running approximately parallel to a sloping shoreline.

Fundamentals of the vibratory driving of piles and sheet piles
geotechnik, 2017AbstractVibratory driving is a common method for installing or extracting piles and sheet piles as well as for deep vibratory compaction. The most important parameters are vibration frequency, vibration amplitude and eccentric moment. These parameters govern vibratory driving and, in particular, the soil resistance at the toe and along the shaft of a ...

Underwater noise and transmission loss from vibratory pile driving
The Journal of the Acoustical Society of America, 2014High levels of underwater sound can be produced in vibratory pile driving that can carry regulatory implications. In this presentation, observations of underwater noise from vibratory pile driving made with a vertical line array placed at range 17 m from the source (water depth 7.5 m) are discussed, along with simultaneous measurements made at ranges ...
