Numerical simulation of screw displacement pile interaction with non-cohesive soil
Archives of Civil and Mechanical Engineering, 2014A trial numerical simulation of screw displacement pile interaction with non-cohesive subsoil during the transfer of compression load is described. The simulation was carried out in an axisymmetric system using the Plaxis 2D-FEM computer programme. The technological phases of pile installation in the ground were numerically modelled using equivalent ...

Towards a Pile Quality Prediction for Screw Displacement Piles Using Bayesian Networks
Information Technology in Geo-Engineering, 2019For screw displacement piles, there is quite some machine data being gathered during the installation, such as torque, pull down and velocity. However, there is no systematic way to process these data and knowledge from the engineer and machinist, neither during nor after the installation stage.

Performance of screw–shaft pile in sand: Model test and DEM simulation
Computers and Geotechnics, 2018A screw–shaft pile is a bored, cast-in-situ, displacement foundation solution. This study examines the performance of axially loaded screw–shaft piles by laboratory model tests, digital image correlation, and discrete element modelling.

CPT-based axial design of screw displacement piles in granular soils
Proceedings of the Institution of Civil Engineers - Geotechnical EngineeringScrew displacement piles are designed to maximise soil displacement, while minimising the noise and vibration generated from installation. While these benefits have increased the uptake of screw displacement piles in the industry, divergences in design standards means there is no definitive consensus on the axial response of these piles.

ABSTRACTDrilled displacement (DD) piles with a screw-shaped shaft (referred to as DD piles) are installed using a continuous full thread hollow rod (without a displacement body) inserted and advanced in the soil by both a vertical force and a torque.

AbstractThis technical note presents a detailed field study to investigate the installation effects of drilled displacement (DD) piles with a screw-shaped shaft in Shanghai soft clay. Horizontal soil displacements and pore water pressures were measured in the vicinity of two DD piles with a screw-shaped shaft during their installation and subsequent ...
