Abstract

The paper introduces the study research on the SH0´s transmission ability in the grounding flat steel, the effects of structural parameters and modalities and the capability of testing defects of SH0. The experimental results show that SH0 waves have a strong transmission ability in flat steel. A maximum depth of 90cm in the soil can be detected. It is expected that the ultrasonic guided-wave SH0 can be a promising measure for NDD of corrosion defects in ground grid.
