Abstract
The low-strain impact method is one of the most commonly used non-destructive geophysical methods in pile integrity testing. Data analysis of the low-strain method in the frequency domain allows the researcher to get additional information about the studied foundation. The authors of the article propose a methodology for assessing the contact of piles with soils based on an analysis of the dynamic attributes of the frequency response. Conclusions drawn from using the above-described method can be used by engineers to study piles quality and to plan direct static load tests to determine the bearing capacity of piles.
