Effects of the tip location on single piles subjected to surcharge and axial loads. [PDF]
ScientificWorldJournal, 2013 When applying axial load on piles subjected to negative skin friction (NSF), the yielded NSF is gradually eliminated. The process is notably influenced by the tip location (Y) and still a lack of understanding.

Numerical analysis of group effect on dragload on piles subjected to negative skin friction [PDF]
Journal of Engineering Research - Egypt, 2022 In this paper, the group effect on dragload on pile group subjected to negative skin friction is studied. The effect of pile spacing, pile location in a group and pile number is studied using finite element program PLAXIS 3D. Single pile, 2x2 pile groups

Behaviour of single pile in consolidating soil
Alexandria Engineering Journal, 2015 Piles located in consolidating soil are subjected to indirect loading resulted from the settlement of adjacent soil. Both pile and soil undergo downward movements caused by the axial pile load and surcharge loading on surrounding area.

Analysis of Influence Factors of Negative Skin Friction on PHC Pile in High-Backfill Sites
Frontiers in Physics, 2022 It is recognized that NSF on a pile affects the structural and geotechnical design. The formation of NSF on a pre-stressed high-strength concrete (PHC) pile under a control building in a Vietnamese project was investigated using a verified numerical ...

Group effect of dragload in pile groups embedded in consolidating soil under embankment load
KSCE Journal of Civil Engineering, 2016 In this paper, model tests and numerical simulations on 3 × 3 pile group embedded in consolidating soil under embankment load with different pile spacings are carried out. Single pile and 2 × 2 pile group are studied for comparative analyses. The performances of dragload versus relative displacement of pile-soil, load sequence and load rate, and the ...

Mathematical Model and Analysis of Negative Skin Friction of Pile Group in Consolidating Soil [PDF]
Mathematical Problems in Engineering, Volume 2013, Issue 1, 2013., 2013 In order to calculate negative skin friction (NSF) of pile group embedded in a consolidating soil, the dragload calculating formulas of single pile were established by considering Davis one‐dimensional nonlinear consolidation soils settlement and hyperbolic load‐transfer of pile‐soil interface.

A Systematic Experimental Study on the Group Effect of Dragloads in Pile Foundations
KSCE Journal of Civil Engineering, 2020 There is a paucity of systematic experimental studies on the group effect of dragloads in pile foundations. This paper reports on a series of 1-g model tests that were conducted on single piles as well as 2 × 2 and 3 × 3 pile groups with various pile spacings to investigate the influence of soil compressibility, pile installation method, pile end ...

Numerical analysis of negative skin friction on piles in soft clay
HBRC Journal, 2013 Negative skin friction is considered one of the problems in the design of piled foundations in soft soil. The negative skin friction induces an additional compressive force on the pile called the dragload as well as, an additional pile movement called ...
