Analysis of the bearing capacity of continuous flight auger piles in terms of their excavation energy and of rainfall data [PDF]
MATEC Web of Conferences, 2021 Continuous flight auger piles (CFAs) are among the most common types of foundation executed in the tropical residual soil of Brasília, DF, Brazil. The bearing capacity of CFAs can be controlled according to the energy required to excavate each pile but ...

Behavior of CFA and H-section steel piles in lateral loading: experimental and numerical analysis
Revista IBRACON de Estruturas e Materiais, 2021 : The behavior of continuous flight auger (CFA) piles and steel H-section piles to lateral loading is investigated using numerical analyses supported by field tests. A three-dimensional finite element numerical model to lateral load is presented.

Results of the “DPDT-Auger” Research Project on Screw Displacement Piles
Architecture, Civil Engineering, Environment, 2023 The main objective of the “DPDT-Auger” research project was to test the prototype DPDT auger for forming screw displacement piles in the ground (patented in Poland in 2020). An additional aim was to develop design methods and rules for the making of such

Just-in-Time Continuous Flight Auger Piles Using an Instrumented Auger [PDF]
Proceedings of the International Symposium on Automation and Robotics in Construction (IAARC), 2002 Continuous flight auger (CFA) piles are constructed by drilling a CFA auger into the ground and, on reaching the required depth, pumping concrete down the hollow stem as the auger is steadily withdrawn. Current practice to predict the bearing capacity of CFA piles is to estimate the undrained shear strength-depth relationship for the overall site, and ...

Some observations on statnamic pile testing [PDF]
, 2006 Limited guidance on usage and methodology is currently available to engineers for the most common rapid load pile test, known as Statnamic. In order to improve the analysis of Statnamic testing in clay soils a full-scale instrumented auger bored pile was

Towards building a neural network model for predicting pile static load test curves
MATEC Web of Conferences, 2018 In the United Arab Emirates, Continuous Flight Auger piles are the most widely used type of deep foundation. To test the pile behaviour, the Static Load Test is routinely conducted in the field by increasing the dead load while monitoring the ...
