Geometric Effects on Piles in Consolidating Ground: Centrifuge and Numerical Modeling
Although semi-open H piles have been widely used, geometric effects (GEs) on H-shaped piles in consolidating ground subjected to negative skin friction (NSF) and downdrag are still not well investigated or understood.

Modélisation numérique des fondations profondes soumises à du frottement négatif [PDF]
RÉSUMÉ: Dans la dernière décennie, une multitude de chercheurs et d'ingénieurs ont travaillé sur la prédiction des charges pouvant être transmises à un système de fondations profondes par l'entremise d'un sol en processus de consolidation.

Evaluation of negative skin friction effects in pile foundations using 3D nonlinear analysis
The aim of this paper is to evaluate the influence of negative skin friction in pile foundations. Three dimensional nonlinear analyses for a single pile and pile groups were carried out for a specific case and some case studies as well.

Negative skin friction (NSF) is a phenomenon which occurs when soil surrounding the piles settles more than piles due to consolidation. NSF may result in dragload and engineering problems such as: differential settlements, damage on the piles and ...

Centrifuge modelling of behaviour of piles in consolidating ground
The development of Negative skin friction (NSF) is regarded as a common problem in the design and construction of pile foundations in consolidating ground.

Development of downdrag on piles and pile groups in consolidating soil
Development of pile settlement (downdrag) of piles constructed in consolidating soil may lead to serious pile foundation design problems. The investigation of downdrag has attracted far less attention than the study of dragload,over the years.

Tunnelling under pile groups and rafts: Numerical parametric study on tension effects
Unfavourable tensile stress can be induced in piles due to tunnelling underneath, as observed in a few recent case histories. Systematic studies of the characteristics of the tunnelling-induced tensile force in pile groups and piled rafts, however, are ...

Negative skin friction on piles in consolidating ground
Pile foundations located within consolidating ground are commonly subjected to negative skin friction (NSF) and failures of pile foundations related to dragload (compressive force) and downdrag (pile settlement) have been reported in literature.

Numerical analysis of pile groups in multi-layered soil subjected to negative skin friction [PDF]
Several linear elastic and nonlinear slip models are reported in the literature for predicting negative skin friction on piles and pile groups in consolidating soils. They often produce significantly different results.

3D Numerical Modeling of Pile Group Responses to Excavation-Induced Stress Release in Silty Clay
Development of underground transportation systems consists of tunnels, basement construction excavations and cut and cover tunnels which may encounter existing pile groups during their construction. Since many previous studies mainly focus on the effects
