| 摘 要： | 根据超声波检测混凝土裂缝深度时接收信号首波相位反转的原理，提出了用正波法检测及确定裂缝深度。在首波相位发生反转变化的临界点上，要用换能器对称和不对称布置测量裂缝深度，均可获得满意的结果。

| Abstract: | According to the theory of the reversion of initial wave phase in ultrasonic testing of the depth of the cracks in concretes, the method for detecting cracks and estimating their depth with positive pulses was put forward. Transducers were disposed symmetrically and asymmetrically to test the depth of cracks at the critical point of the phase reversion, and the experimental results were satisfactory. |
