Laboratory Model Study on the Pile-Forming Mechanisms and Bearing Deformation Characteristics of CFA Piles [PDF]
Advances in Civil Engineering, 2021 To study the pile-forming mechanism and bearing deformation characteristics of continuous flight auger (CFA) piles, a series of procedures, including helical drilling, pulling up/grouting, and inserting cage/pile forming, were simulated in clay-sand ...

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.

Remoulding of the Mercia Mudstone Group around CFA pile shafts [PDF]
Quarterly Journal of Engineering Geology and Hydrogeology, 2013 A field test has been undertaken to investigate changes to in situ Mercia Mudstone at the pile soil interface after installation of four 5.5 m long 350 mm diameter CFA piles. The test investigated whether a remoulded zone exists, the extent of the zone,

Long Term Monitoring of CFA Energy Pile Schemes in the UK [PDF]
, 2016 Energy pile schemes involve the use of structural foundations as heat exchangers in a ground source heat pump system. Such schemes are attractive, as they reduce energy consumption compared with traditional building heating and cooling systems. As energy

Axial resistance of CFA piles in Dublin Boulder Clay [PDF]
Proceedings of the Institution of Civil Engineers: Geotechnical Engineering, 2008 This paper describes the results of static compression and tension load tests performed on three-instrumented large-diameter continuous flight auger piles installed in Dublin Boulder Clay. The piles developed very high shaft resistance and, in contrast to piles driven into Boulder Clay that exhibit friction fatigue, the shaft distribution was uniform ...
