Numerical analysis of group effect on dragload on piles subjected to negative skin friction [PDF]
, 2023 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

Liquefaction-induced Dragload and/or Downdrag on Deep Foundations within the New Madrid Seismic Zone [PDF]
, 2018 Deep foundation elements are typically used to transfer structural loads for multi-story buildings and large-span bridges to a competent soil layer when 1) the soil close to the ground surface has no sufficient bearing capacity, and when 2) liquefiable ...

Calculating Pile Downdrag: Experimental and Numerical Investigations [PDF]
, 2021 Piles can be exposed to significant settlement (i.e., downdrag) and compressive force (i.e., dragload) if embedded in consolidating ground. Downdrag has been included in the design of piles, but there is uncertainty about how downdrag and dragload are ...

Dragload of pile groups in consolidating non-Darcian clays
, 2018 In the present study, the behaviour of pile groups with flexible cap in consolidating non-Darcian soil is investigated in terms of dragloads and downdrag.

Effects of Tip Location and Shielding on Piles in Consolidating Ground
, 2008 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 the literature. This

Comparative study of Y-shaped and circular floating piles in consolidating clay
, 2016 Although engineers often make use of pile geometry to improve the axial load capacity of piles, geometrical effects on floating piles in consolidating clay are still not fully understood.

Shielding piles from downdrag in consolidating ground
, 2013 Negative skin friction (NSF) can induce an increased compressive force on piles, called dragload, and additional pile settlement caused by the downward pull of the soil, called downdrag.

Field Investigation of Influences of Load on Pile Top on Negative Skin Friction Behaviors
, 2011 In order to study influences of applied load on pile top on the negative skin friction behaviors of piles, field investigations of negative skin friction behaviors of three identical piles with different loads on pile top are made in the same site.

The Responses of an End-Bearing Pile to Adjacent Multipropped Excavation: 3D Numerical Modelling [PDF]
, 2019 It is well recognised that superstructure load is transferred to surrounding soil through piled foundation. Consequently, the high stress regime (stress bulb) is generated surrounding of the pile.
