| Abstract: | An embedment depth measurement system with corresponding software of signal processing for ultrasonic guided wave inspection was developed. With this system, an in-situ testing of guardrail post under typical operating conditions was carried out. Research results showed the accessories and embedment medium of guardrail post have little effect on the measurement precision. Additionally, this system has some features such as high measurement precision, easy waveform identification and convenient inspection. In conclusion, ultrasonic guided wave technique has outstanding advantages and application potential in the guardrail post embedment depth measurement. |
