Damage Evaluation of Bond Surface in Concrete by Elastic Wave

在这项研究中，混凝土表面裂缝和内部缺陷的弹性波技术进行了调查。结果，在通过共振传感器检测弹性波的情况下，可以通过使用弹性波速度来评估表面裂纹。此外，还对在役钢筋混凝土构件进行了弹性波检测。采用弹性波速度层析成像方法识别混凝土构件表面裂缝和内部缺陷。

In this study, surface cracks and internal defects in concrete were investigated by elastic wave techniques. As a result, surface cracks could be evaluated by employing elastic wave velocity in the case that elastic waves were detected by resonance sensor. In addition, elastic wave techniques were applied to reinforced concrete members in-service. Surface crack and internal defects in the concrete memberswere identified by tomography method of elastic wave velocity.
