A Study of Design Procedures for Augered Cast-In-Place-Piles in Clay
Abstract
The augured cast pile is a type of cast-in-place pile developed in the United States over 50 years ago. Although the performance of augered cast-in-place piles (ACIP) are highly construction dependent, ACIP piles have became an increasingly popular choice for deep foundations systems, due to low construction cost, ease of construction, and their applicability to a wide variety of soils. The methods generally used for prediction of capacity are methods that were originally developed for drilled shafts. This paper reports on the study of how current design methods from predicting ACIP pile capacities in clay compare to capacities obtained from load tests. ACIP pile load test data are interpreted using various published methods to determine pile capacity. These capacities are then compared with predictions of capacities from various theories. The current design methodologies used to predict capacities in cohesive material are ultimately evaluated and recommendations are made based upon analysis of the data from the pile load tests.
