Abstract: A two-dimensional (2D) time-domain waveform tomography technique is presented for detection of delamination in concrete bridge decks. Measured ultrasonic surface wave fields were inverted using a full waveform inversion ...

Abstract: A new ultraseismic waveform tomography technique for a bounded medium is presented for evaluation of concrete bridge abutments, or wall piers, and the supporting soil and rock underneath them. Ultraseismic wave fields are ...
