Abstract: Site characterization for the design of geotechnical structures such as deep foundations is crucial, as unanticipated site conditions still represent the most common and most significant cause of problems and disputes that ...

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 ...
