説明

Ultrasonic (SH wave) measurements are used to measure the penetration length and investigate corrosion of metal pillars that are road accessories such as guardrails, lighting poles, and signposts. In on-site measurements, measurements are performed while subtly adjusting the pressing force and direction of the sensor based on the experience and skill of the measurer in order to obtain as large a reflected wave as possible. However, there are differences in the measurement results regarding the sensor pressing force depending on the experience of the measurer. Therefore, in this study, we quantitatively measured the difference in the sensor contact surface and pressing force in on-site measurement using ultrasound (SH waves) by a measurer, and clarified the difference.
