High-Capacity Piles at the Stony Creek Bridge Project.

High Capacity Piles (HCP) offer a highly attractive foundation option to geotechnical designers, but they continue to present challenges to regularacceptance and wider implementation. Through a case study of the Stony Creek Bridge Project, the California Department of Transportation presents its experience with the advantages and limitations of High Capacity Piles. The motivating reasons, design considerations, construction observations and testing results at the Stony Creek Bridge are detailed to allow insightinto this developing foundation choice. The 8-foot (2.44m) diameter 170-foot (51.8m) long steel piles at the Stony Creek Bridge are reputed to be the largest piles ever driven on land.
