Why Frequency Domain Analysis?
The analysis in the time domain is relatively simple to interpret and assesses the location of major defects. The analysis in the Frequency Domain computes the relative mobility and dynamic stiffness of the pile. Coupled with the Multiple Column plot, it allows the comparison of records from various piles from the same location. Dynamic stiffness yields a relative assessment of pile strength and quality. The Pile Profile Analysis generates a plot of pile impedance as a function of depth for piles with a clear toe.
