• Abstract:
  A new methodology to estimate unknown pile length called Effective Dispersion of Reflections (EDAR) was developed. A software package was also developed for seamless application of the methodology. EDAR software facilitates data acquisition in the field and the subsequent analysis of the data to estimate pile length. In addition to providing length estimates, EDAR has the ability to estimate some of the material property of the pile. EDAR was validated successfully for Concrete Filled Steel Tube (CFST) piles at various locations in Alaska. This report contains the details of EDAR methodology, testing, step-by-step instructions for the software, as well as the details of the testing equipment and the underlying theory.
