Abstract
Surface acoustic measurements in examining pile foundations is increasingly used in practice, as it is an effective tool for the measuring the length and defects of piles. However, this method for diagnostics of monolithic pile structures, for example, bored piles, can lead to significant measurement errors. This is because the propagation velocity of acoustic waves in a bored pile is usually calculated theoretically, and many factors affecting the propagation velocity of acoustic waves are not taken into account. According to earlier research, dual channel acoustic measurements used to determine the length of bored piles, makes it possible to accurately calculate the propagation velocity of acoustic waves and, accordingly, the pile length. It is shown that dual channel acoustic measurements applied to bored piles allow detecting with sufficient accuracy such defects as cross-sectional deviations of the pile shaft along its length.
