超声波法检测灌注桩的桩身完整性是一种较好的测试方法。本文通过工程实例，阐述了用超声波法检测的可靠性。同时根据超声波法检测的特点，结合混凝土的性能，可采用“声速－振幅－波形”综合法来判定混凝土缺陷。

Inspecting the integrity of a cast-in-place pile shaft with an ultrasonic wave test is afairly good method. This paper, through a practical engineering case, describes the reliability ofthe ultrasonic wave test. Simultaneously,concrete defects may be determined by a synthetic methodof "velocity of sound -amplitude of vibration-wave form" on the basis of the features of theultrasonic wave test and concrete property.
