Abstract

Occurrence of crack in the Half-loc of rubble mound breakwater under T.T.P (Tetrapod) can cause serious problems in structural safety. There, probing of such cracks in marine structures is an important process in evaluating the overall integrity of structures. Ultrasonic, SASW(Spectral-Analysis-of-Surface-Waves)and Impect-Echo methods were used for the inspection of pilot concrete and SFC (Steel Fiber Concrete) block in this study. The advantage and limitations of these methods for non-destructive inspection in concrete blocks are investigated. As a result, it has been verified that these methods proved to present effective solution for detecting the crack of the pilot concrete block.
