| Summary | In terms of maintenance of road structures, it is important to clarify the soundness of structures. However adequate methods to detect abnormality and evaluate soundness have not been established in many kinds of damage in road structures. In the study, we researched the applicability of the impact elastic wave method and the ultrasonic wave method to detect prestress degree of PC structures. |
