Viscoelastic analysis of piles and pile groups

International Journal for Numerical and Analytical Methods in Geomechanics, 1985
AbstractThe axial and lateral load–displacement response of single piles and pile groups during the secondary consolidation (creep) phase of deformation is obtained by idealizing the soil as a linear viscoelastic material. The boundary element method is used to model the soil halfspace and the piles, which are assumed to behave elastically, are ...

Numerical Analysis of Pile–Soil–Pile Interaction in Pile Groups with Batter Piles

Geotechnical and Geological Engineering, 2018
Battered piles are usually used to counteract lateral forces in a pile group. As there is little spacing between piles, they are affected by one another, and there is interaction between them. In this study, pile–soil–pile interaction in a group of battered piles was numerically simulated using finite element analysis. Double and frictional pile groups

Pile Cap-Pile Group-Soil Interaction

Journal of the Structural Division, 1981
A numerical procedure based on the finite element method is proposed for the analysis of structural systems composed of beam-column (pile), plate (cap) and nonlinear springs (soil). It integrates one-and two-dimensional idealizations for these components in order to obtain an approximation to the three-dimensional problem.

The Elastic Analysis of Compressible Piles and Pile Groups

Géotechnique, 1971
Synopsis The response of rigid and compressible single piles embedded in a homogeneous isotropic linear elastic medium has been obtained by a rigorous analysis based on Mindlin's solutions for a point load in the interior of an ideal elastic medium. The analytical method is described and is extended to analyse axially loaded rigid and compressible ...

The Problem of Pile Group–Pile Cap Interaction

Géotechnique, 1971
Synopsis The Paper presents an elastic analysis of two problems concerning the interaction with the supporting ground of an arbitrarily spaced group of piles, embedded in a smooth ground contacting pile cap of any shape, namely the load displacement behaviour of the system and the load distribution between the piles in the group and the cap.

Load Transfer Mechanisms in Piles and Pile Groups

Journal of the Geotechnical Engineering Division, 1982
This paper describes patterns of measured load transfer in a full-sized instrumented pile group; subgroups within the main group; and in single control piles loaded in compression. The effects of residual stresses and uplift loading on load transfer are also described.

Optimisation of pile groups

Computers and Geotechnics, 1987
Abstract The optimisation of pile groups is studied using an optimisation technique in conjunction with a discrete element method for pile group settlement analysis. It is demonstrated that it is possible to optimise the performance of pile groups by minimising the load differentials between piles and/or differential settlements.

Uplift Capacity of Piles and Pile Groups in Sand

OCEANS '86, 1986
Offshore structures supported by pile foundations are sometimes subjected to uplifting forces due to wave, wind, and ice actions. This paper presents the results of laboratory model tests for ultimate uplift capacity of single and group metal piles embedded in saturated medium and dense sand. The results have been compared with existing theories.

Simplified Calculation Approach for Settlement of Single Pile and Pile Groups

Journal of Computing in Civil Engineering, 2012
AbstractThis paper proposes a simple analytical approach for nonlinear analyses of the load-displacement response of single piles and pile groups. Two models were adopted in the proposed approach. One model is based on a hyperbolic nonlinear relationship to simulate the behavior between unit skin friction and pile displacement developed along the pile ...
