최근 콘크리트전주 절손사고가 지속적으로 발생하고 있다. 현재 사용중인 콘크리트전주는 프리스트레스트 콘크리트구조로 이루어져 있으며, 전선 장력에 의한 모멘트 하중에 효과적으로 작용하도록 설계되어 있다. 그러나 시간의 경과에 따라 열화현상이 발생하며 이로 인하여 콘크리트 내부에 매입된 강선이 부식됨으로 인하여 전주의 건정성이 저하된다. 이에 따라 콘크리트전주 절손 사고의 근본적인 원인을 파악하고 사고를 방지할 수 있는 방안을 마련하기 위해 본 연구를 진행하였다. 본 논문에서는 콘크리트전주 내부 강선의 이상유무를 진단하는 방법 및 장비를 개발하였다.
