【Abstract】 This paper gives a description of the basic theory and principle of supersonic sounding technology for steel pipe concrete and its application in detection of steel pipe concrete of Wushan Changjiang River Bridge. This technology is mainly used to detect the compactness of the concrete in the steel pipe, whether any cavity exists in it and any gap present between the inner wall of steel pipe and concrete.更多还原
