Piled raft with hollow auger piles founded in a Brazilian granular deposit

Canadian Geotechnical Journal, 2015
Geotechnical projects typically achieve load transfer to the ground using shallow or deep foundations. The conventional design approach does not provide for the combination of these two types of foundation. The piled raft philosophy allows the association of the soil elements, raft, and piles to obtain technical and economic advantages over ...

Einsatz und Anwendungsgrenzen von Schneckenbohrpfählen (Auger‐cast‐in‐place Piles – ACIP‐Piles)

Bautechnik, 2014
AbstractFür die Gründung einer Düngemittelanlage in Port Neal/Iowa wurden durch den Bauherrn Schneckenbohrpfähle (sog. ACIP‐Piles) als Gründungsentwurf vorgegeben. Angesichts der bis in große Tiefen unterhalb des Grundwassers anstehenden, sehr enggestuften, feinkörnigen Sande wurde die Ausführung im Hinblick auf DIN EN 1536 als kritisch eingestuft.

Design Methods for Auger CIP Piles in Compression

New Technological and Design Developments in Deep Foundations, 2000
This paper reports on a study of 43 compression load tests (5 fully instrumented) and 10 pullout tests of auger cast-in-place (ACIP) piles in sand. Eight design methods reported in the literature were used to predict the measured pile capacities. Ultimate load capacities of the ACIP load tests were determined using two different definitions of ultimate

Testing of Augered Cast-in-Place Piles Installed with Varying Auger Rotations

Full-Scale Testing and Foundation Design, 2012
Augered cast-in-place piles are installed by the excavation of the soil by rotation of a continuously flighted auger into the ground and then placement of a fluid cement grout into the evacuated volume as the auger is extracted. The soil conditions immediately after excavation for augered cast-in-place piles will be related to the in situ soil ...

Axial Capacity of Augered Displacement Piles at Auburn University

New Technological and Design Developments in Deep Foundations, 2000
A comparative study as performed at the Auburn University's Spring Villa NGES test site aimed at quantifying the effects of grouping and amelioration on the axial capacity of augered displacement piles. Amelioration is defined as the addition of sand or stone during drilling to "improve" the pile-soil interface.

Bearing Capacity of Auger‐Cast Piles in Sand

Journal of Geotechnical Engineering, 1991
Auger‐cast piles are formed by drilling a continuous flight auger into the ground and, on reaching the required depth, pumping grout or concrete down the hollow stem as the auger is steadily withdrawn. The sides of the hole are supported by the soil‐filled auger, eliminating the need for temporary casing or bentonite slurry.

Load-settlement curve of continuous flight auger piles

2015
It is estimated that the continuous flight auger piles currently represent about 75% of the market for deep foundations for buildings in Recife. Therefore, it is essential to know the performance of such piles, in order to optimize the design of foundations.
