Influence of grout injection parameters on shaft bearing capacity of screw displacement piles
, 2022 This document describes the test program that was conducted in 2021 to investigate the influence of grout injection parameters on the shaft bearing capacity of screw displacement piles. Grout variants considered were water/cement ratio, blend composition and flow rate.

Unraveling deformation mechanisms around FCC and BCC nanocontacts through slip trace and pileup topography analyses [PDF]
, 2017 Nanocontact loadings offer the potential to investigate crystal plasticity from surface slip trace emissions and distinct pileup patterns where individual atomic terraces arrange into hillocks and symmetric rosettes.

Set-up effects of piles in sand tested in the centrifuge [PDF]
, 2014 The bearing capacity of piles increases over time. Research has shown that this is caused by an increase in shaft friction combined with a constant or only slightly increasing base capacity.

Effect of grain disorientation on early fatigue crack propagation in face-centred-cubic polycristals: A three-dimensional dislocation dynamics investigation [PDF]
, 2013 Three-dimensional dislocation dynamics simulations are used to study micro-crack interaction with the first micro-structural barrier in face-centred cubic bi-crystals loaded in high cycle fatigue conditions. In the examined configuration, we assumed that

Design and Manufacturing Loading Rig Machine for Testing Screw Pile Models
International journal of engineering and technology, 2018 The main objective of this paper is to design, manufacturing and testing of new loading rig machine to install and testing (i.e. compression and tension load capacity) of screw pile models in both cohesive and cohesionless soil layers. The mainframe was

Design and Applications of Drilled Displacement (Screw) Piles
, 1969 Drilled displacement (DD) piles (commonly known as „screw piles‟ in Europe) are being increasingly used as foundation elements for structures, particularly in projects requiring accelerated construction or involving the rehabilitation of foundations of existing, overstressed structures.

, 2020 Existing guidance on the installation of screw piles suggest that they should be installed in a pitch-matched manner to avoid disturbance to the soil which may have a detrimental effect on the in-service performance of the pile.

CHD pile performance, Part I:Physical modelling [PDF]
, 2016 The Continuous Helical Displacement (CHD) pile is an auger displacement pile developed by Roger Bullivant Ltd in the UK. It has performance characteristics of both displacement and non-displacement piles due to the nature in which it is installed.
