Evaluation of group effect of pile group under dragload embedded in clay

Journal of Central South University of Technology, 2009
A simple semi-empirical analysis method for predicting the group effect of pile group under dragload embedded in clay was described assuming an effective influence area around various locations of pile group. Various pile and soil parameters such as the array of pile group, spacing of the piles (S), embedment length to diameter ratio of piles (L/D) and

Dragload and downdrag performances of inclined pile group embedded in consolidating soil

Transactions of Tianjin University, 2011
The performance of inclined pile group embedded in consolidating soil under surcharge load was investigated by experiment in comparison with vertical pile group and single pile under the same conditions; dragload, downdrag, and layered soil settlement were measured.

Fully Coupled Consolidation Analysis of Shear Strength Mobilization and Dragload of a Pile Subject to Negative Skin Friction

International Journal of Geomechanics, 2015
Mobilization of negative skin friction (NSF) along a pile shaft increases the axial load (dragload) and pile head settlement (downdrag) of the pile, which may exceed the structural capacity of the pile and violate its serviceability performance, respectively.

Dragload and Downdrag Settlement of Single Piles due to Post-liquefaction Reconsolidation

2016
A fundamental error with the traditional neutral plane solution is that the neutral plane solution assumes that the pile settlement and soil settlement are equal at the depth of the neutral plane. However, it is the relative velocity, not the relative displacement that must be zero at the neutral plane depth.

Numerical modelling of group effects on the distribution of dragloads in pile foundations

Géotechnique, 2002
Negative skin friction on pile foundations, predicted from the results of numerical analyses, is presented. Soil slip at the pile–soil interface has been found to be the most important factor in governing pile behaviour in consolidating ground. Reduction in dragload is predicted for piles in a group owing to interaction between soil and pile.

Development of Negative Skin Friction and Dragloads on Piles and Pile Groups in Soft Clay

2018
One of the challenging problems that faces geotechnical engineers in pile design in soft soils is the determination of negative skin friction (NSF) value. Negative skin friction causes additional compressive force on the pile, which decreases the pile carrying capacity.

Influence of twin stacked tunnels on the performance of laterally loaded pile group

Canadian geotechnical journal (Print)
This research utilized three-dimensional centrifuge model experiments and back-analyses with a hypoplastic model to assess the performance of a laterally loaded 2×2 pile group subjected to twin stacked tunneling at different depths.
