Abstract:Monitoring installation of driven pile foundations
is critically important to ensure adequate safety
of structures with piles, such as the many bridges
which are maintained by the Florida Department
of Transportation (FDOT). Dynamic load testing
of driven piles is currently the method preferred
by industry because it is cost effective and
reliable for assessing static capacity. Prior to
the use of the Embedded Data Collector system
(EDC) in construction, dynamic load testing was
accomplished using the pile driving analyzer
(PDA), coupled with CAPWAP (Case Pile Wave
Analysis) and wave equation analysis. This method
involves external gauges fixed to the top of the
pile, from which stresses and capacity vs. depth
are computed using the Case capacity equation
with the Case lumped damping parameter.
