• Abstract:
  The Maine Department of Transportation (MaineDOT) has noted poor correlation between predicted pile resistances ; calculated using commonly accepted design methods and measured pile resistance from dynamic pile load tests (also ; referred to as high strain dynamic tests) conducted in accordance with ASTM D-4945. The MaineDOT requested ; that the University of Maine examine and evaluate their current static pile capacity design methodologies using the ; results from dynamic load tests on piles as a standard. The authors have used the term capacity in this report since ; the reports for the dynamic load test database used capacity, and most references used capacity. Capacity can be ; used interchangeably with the term ‘resistance’ used by AASHTO in LRFD applications. The intent of the final ; product is to provide MaineDOT with calculation methods that provided the most reliable capacity estimates. More ; reliable calculation methods will result in more cost efficient designs. The work which went into this report was ; essentially divided into two phases: the creation of a database which encompassed selected, available project data ; and comparison of static capacity analysis methods to investigate which combination is most reliable. The second of ; the two phases is detailed in this report.
