Abstract This Geotechnical Engineering Circular (GEC) is intended to provide recommended guidance for the LRFD design, analysis, and testing of laterally loaded deep foundations for transportation facilities. This document applies to deep foundation elements such as driven piles, drilled shafts, micropiles, and continuous flight auger (CFA) piles that are used to resist lateral loads, often in combination with axial loads, for new construction, rehabilitation, or reconstruction of transportation facilities. Applications include both single and groups of deep foundation elements for bridge foundations, excavation support, earth retention structures, noise walls, sign and signal foundations, landslide repairs, vessel or vehicle impact mitigation measures, and seismic event resistance. The objective of this document is to provide a single reference source for the state-of-the-practice with regard to recommended methodologies and guidance for the design, analysis, and testing of laterally loaded deep foundations for transportation facilities. 17.
