Abstract

Ultrasonic cross-hole detection method is widely used for the quality detection of bored piles due to its comprehensive, detailed and accurate results, and no restrictions on the lengths and ratios of length to diameter of piles. However, because of the quality problems of the instrument or operation rather than the quality of the pile itself, the ultrasonic testing results are not good enough, and the misjudgment often occurs. The paper analyzed the characteristics and the causes of the problems, and discussed how to identify and reduce the occurrence of misjudgment by summarizing the experiences from the ultrasonic testing results of the 5,000 piles for the 53km North-South Expressway project in Algeria, and combining relevant specifications and literatures.
