Abstract: The ability of the spectral analysis of surface waves (SASW) test to detect underground obstacles has been investigated. The SASW test is simulated by the finite-element method. The fluctuations in the dispersion curve, ...

Abstract: Ultrasonic seismic methods can be used in the condition assessment of bridge decks by evaluating changes in material characteristics and detecting the development of defects and zones of deterioration. The impact-echo ...
