Pile Spacing Effects on Lateral Pile Group Behavior: Load Tests
Journal of Geotechnical and Geoenvironmental Engineering - ASCE, 2006To investigate group interaction effects as a function of pile spacing, full-scale cyclic lateral load tests were performed on pile groups in stiff clay spaced at 3.3, 4.4, and 5.65 pile diameters in the direction of loading with as many as five rows of piles. Group interaction effects decreased considerably as pile spacing increased from 3.3 to 5.65D .

Effect of Pile Arrangements on the Dynamic Coupled Response of Pile Groups
Geotechnical and Geological Engineering, 2020This paper presents both experimental and analytical investigation to monitor the effect of dynamic pile-soil-pile interaction on the nonlinear coupled response of a 6-pile group placing in different arrangements of piles under rotating machine induced vibrations.

Effects of Pile Cap in Single Pile and Lateral Capacity of Pile Group
Advances in Deep Foundations, 2005This paper describes the results for a numerical analysis of single piles and pile groups in clayey soils subjected to monotonous lateral loading using the ABAQUS finite element software. The investigated variables in this study include free head and embedded capped single piles, pile diameter (1.0 m, 0.5 m), pile length (7.0 m, 10.0 m), and pile ...

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.

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

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 ...

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.

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.

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.
