• 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.
