• Field testing and calibration of EDAR Method for Estimating Embedded Depth of Pile Foundations in North Carolina

    NCDOT Research Project Number: 2018-29

Executive Summary

  • A new methodology to estimate the unknown pile length called Effective Dispersion Analysis of Reflections (EDAR) was developed. EDAR explicitly incorporates the dispersion properties of the wave generated on hammer impact to provide a pile length estimate. A software package was developed for seamless application of the EDAR methodology facilitating data acquisition in the field and subsequent analysis of the data to estimate the pile length. EDAR has been validated successfully in laboratory and field conditions in North Carolina. The report contains the details of EDAR application for prestressed concrete piles including details of testing equipment, testing, stepwise analysis procedure, and the underlying theory.
