Lateral dynamic response of pile group embedded in unsaturated soil
, 2021A mathematical formulation is proposed for the analysis of a pile group embedded in unsaturated soil subjected to horizontal time-harmonic vibration. The unsaturated soil is governed by the motion theory of three-phase poroelastic medium, and the piles ...

Piles are usually installed in both onshore and offshore sites to transit the structural loads through soft or loose soil layers to competent soil strata. Although the installation of a single pile is usually considered to be undrained, consolidation may

Tunnel excavations inevitably induce stress release and soil movement, which may affect the safety and serviceability of nearby existing pile foundations. The effects of tunnel construction on existing piles have been extensively investigated, but little

Investigation of the end bearing load in pile group model in dry soil under horizontal excitation
Acta geotechnica slovenica, 2021A series of 94 laboratory tests were conducted to measure the response of pile foundation when subjected to dynamic loads. Eight tests were conducted on single pile in dry soil at relative density 30 % (loose) and 50 % (medium); 66 tests on group of ...

Viscoelastic analysis of piles and pile groups
International Journal for Numerical and Analytical Methods in Geomechanics, 1985AbstractThe 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, 2018Battered 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, 1981A 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.
