Effect of Batter Piles on Static Behavior of Pile Groups
2011Pile group are vastly used in marine structures for several applications. Loadings exerted to these structures are divided into two main categories: lateral loading and vertical loading. All researchers agree to use vertical piles in the case of pure vertical loading where as the use of batter piles in the case of lateral loading is still in doubt. The

Pile Spacing Effects on Lateral Pile Group Behavior: Analysis
Journal of Geotechnical and Geoenvironmental Engineering, 2006Using the results from three full-scale lateral pile group load tests in stiff clay with spacing ranging from 3.3 to 5.65, computer analyses were performed to back-calculate p multipliers.

Effects of actions due to group effect on the superstructure on pile groups
2005An approach based on design charts for the effects of actions due to group effects on the superstructure on pile groups is presented. Therefor an extensive numerical paramtetric study was carried out. A description of the numerical model and comparisons with field load tests and theoretical results are presented.

Boundary Effects of Pile Cap on the Integrity Testing of Group Piles
2018Low-strain surface reflection pile integrity testing (PIT) methods have been successfully used for the quality assurance of newly-built individual piles. However, for existing piles with pile cap, previous studies have shown that the stress-wave reflected from the boundaries of pile cap may cause difficulties in determining their integrity.

Experimental study of the effect of inclined pile on the seismic behavior of pile group
Soil Dynamics and Earthquake Engineering, 2012Seismic behavior of inclined piles has been considered detrimental for years. However, recent researches show that battered piles can have a beneficial effect. In this framework, a series of centrifuge tests on an inclined pile group is performed. The analysis is based on the comparative response of two 2×1 simplified pile groups: one with vertical ...

The effect of negative skin friction on piles and pile groups
2009Piles are often designed to resist axial loads acting on the pile head through the development of positive shaft resistance (PSR) and end-bearing resistance. In addition to the pile head loading condition, shear stresses are mobilized at the pile-soil interface when the soil settles more than the pile in consolidating ground owing to the development of

Effect of air injection on pile and pile group behavior in liquefiable soil
Bulletin of Engineering Geology and the Environment, 2020Soil liquefaction during large earthquakes causes serious damage to structures built on foundations. In recent years, artificially injecting small amounts of air into liquefaction-susceptible soils has been proposed as a newly developed and cost-effective liquefaction mitigation method.

Numerical study of group effects for pile groups in sands
International Journal for Numerical and Analytical Methods in Geomechanics, 2003AbstractThe OpenSees finite element framework was used to simulate the response of 3×3 and 4×3 pile groups founded in loose and medium dense sands. Several numerical static pushover tests were conducted to investigate the interaction effects for pile groups. The results were then compared with those from centrifuge study.

Dynamic group effect in axial responses of grouped piles
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1983Analytical expressions for soil stiffness for a group of piles were obtained for both plane strain and three dimensional conditions. A comparison between these two expressions revealed that a concept of a Winkler soil model could be applicable to pile group problems for the frequency range higher than the fundamental natural frequency of the soil ...

The effect of the propeller jet on pile groups
China Ocean Engineering, 2013The objective of this study is to determine the effect of jet propeller on the damage of berthing structures combined of armoured slope with pile groups. For this purpose, scour measurements were performed for four types berthing structures, which were armoured slope with tandem arrangements of piles for two and three piles and with side by side ...
