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
