EM 1110-2-2906 15 January 91 US Army Corps of Engineers ENGINEERING AND DESIGN Design of Pile Foundations ENGINEER MANUAL DEPARTMENT OF THE ARMY EM 1110-2-2906 US Army Corps of Engineers CECW-ED Washington, DC 20314-1000 Engineer Manual No. 1110-2-2906 15 January 1991 Engineering and Design DESIGN OF PILE FOUNDATIONS 1. Purpose . This manual provides information, foundation exploration and testing procedures, load test methods, analysis techniques, allowable crite- ria, design procedures, and construction consideration for the selection, design, and installation of pile foundations. The guidance is based on the present state of the technology for pile-soil-structure-foundation interaction behavior. This manual provides design guidance intended specifically for the geotechnical and structural engineer but also provides essential information for others interested in pile foundations such as the construction engineer in understanding construction techniques related to pile behavior during instal- lation. Since the understanding of the physical causes of pile foundation behavior is actively expanding by better definition through ongoing research, prototype, model pile, and pile group testing and development of more refined analytical models, this manual is intended to provide examples and procedures of what has been proven essful. This is not the last nor final word on the state of the art for this technology. We expect, as further practical design and installation procedures are developed from the expansion of this technology, that these updates will be issued as changes to this manual. 2. Applicability . This manual is applicable to all mands having civil works responsibilities, especially those geotechnical and structural engineers charged with the responsibility for design and installation of safe and economical pile foundations.
