灌注桩超声波跨孔法检测技术探讨

Preliminarily Studies on Testing Technique of Ultrasound Bridge over the Hiatus of Grouting Pile

超声波跨孔法是以纯纵波声速在无限介质内的传播规律为理论基础,发展起来的一门灌注桩质量检测技术。超声波检测的原理、现场检测、检测过程中应该注意的问题、对检测数据的分析研究和桩身质量判定方法,是章文讨论的重点。

Ultrasound bridge over the grouting pile is a technique of testing to the quality of grouting pile which developed upon the basis of the method of pure longitudinal sound wave velocity propagating in infinite objects. Applying ultrasound testing mehod on spot testing, taking notice of the problem in processing, analysing of the testing data and e-valuating method of the quality of the pile are the main points of this paper.
