Static Capacity Analysis of Augered, Pressure-Injected Displacement Piles
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 resistance in soils where displacement leads to densification. Current augercast design methodologies assume a Ko to Ka condition in the vicinity of the pile, and thus the body of knowledge associated with conventional APG piles would be expected to be a conservative base line from which to begin assessing the capacity APID pile systems. This paper offers an empirical design methodology for APID piles, based on evaluation of 28 load tests, primarily in granular materials and in a variety of geologic settings. A design process that includes modification for soil types within the coarse-grained range is presented for CPT and SPT exploratory information.
