Liquefaction Induced by Auger-Cast Piles: How Common?

Journal of Geotechnical and Geoenvironmental Engineering, 2007
Clear water was observed percolating from the tops of fresh auger-cast piles and from the surrounding ground. This transient event, typically lasting less than an hour, occurred in approximately 40% of nearly 700 piles. The percolating water was apparently due to liquefaction of saturated loose to very loose sand, induced by the auger during ...

Physical modelling of deformations around piling augers in clay

Géotechnique, 2011
Small-scale model tests are reported in which miniature augers were installed in beds of transparent synthetic soil simulating clay. As the auger advanced, the movement of reflective particles seeded into the soil and illuminated by laser light was recorded photographically.

Stochastic Productivity Assessment of Continuous Flight Auger Piles

Architectural Science Review, 2009
Abstract Continuous flight auger (CFA) piles are widely used in the US and the UK as well as in many other countries. This paper focuses on developing simulation models to provide productivity and cost for various pile sizes and depths. Two simulation models were developed. Based on these models, various charts were developed to assess productivity and

Static Capacity Analysis of Augered, Pressure-Injected Displacement Piles

Deep Foundations 2002, 2002
Augered, pressure-injected displacement (APID) piles develop significantly higher capacities than conventional augercast (APG) piles in loose to medium dense, granular materials. During APID installation, a Ko to Kp environment is created in the materials surrounding the pile immediately prior to casting, and this condition results in increased shaft ...

The fundamental behaviour of displacement screw piling augers

2017
The use of both displacement and non-displacement cast in-situ screw piling techniques has seen considerable growth over the last 10 years. In this time, significant advances have been made in the equipment used to install screw piles. The torque capacity of screw piling rigs has increased dramatically from as low as 10 k:Nm for continuous flight auger

Productivity and Cost Assessment for Continuous Flight Auger Piles

Journal of Construction Engineering and Management, 2005
Continuous flight auger (CFA) piles do not receive sufficient research attention although they are widely used in the United States, United Kingdom, and other countries in the world. Therefore, this paper focuses on describing the CFA pile installation features, exploring its construction methods, and determining the factors that affect the CFA pile ...

Special Requirements for Testing Auger-Placed Grout Piles

1979
Experience in testing auger-placed grout piles using ASTM Testing Piles Under Axial Compressive Load (D 1143) indicates that modification of the testing methods for this type of pile can improve interpretation of test data and provide greater confidence in the test results.

Analysis of Lateral Load Tests on Auger Cast Piles

Tunneling and Underground Construction, 2014
This paper evaluates three lateral load tests performed on 406 mm (16-inch) diameter auger cast piles (ACP). The lateral deflection values of the ACP measured in the field are compared with the lateral deflection values of the ACP predicted using a commercial computer program, LPile.
