초록

최근 국내 주요 SOC 시설물의 사용 연수가 30년 이상을 넘어가고 있어, 10년 내 노후화가 급속도로 진행될 것으로 예상되면서 시설물의 선제적 유지관리에 대한 필요성이 대두되고 있다. 이에 따라 유지관리 분야에도 스마트 점검 기술을 도입하기 위한 연구가 다수 수행되고 있다. 하지만 현재 시설물 유지관리는 인력위주의 안전점검 및 진단에 맞춰 제도가 마련되어 있어, 실제 현장에서 육안조사에 의존하여 조사가 이뤄지고 있는 실정이다. 인력점검의 경우 점검시간이 과다 소요되고 결과 분석 시에 주관적인 오류 등이 발생할 수 있으며, 터널의 경우 일부 구간 차단으로 사회간접비용 손실 등이 발생한다는 단점이 있다. 따라서 스마트 안전점검을 제도적으로 도입하기 위해서는 첨단 장비 사용, 전문가 자격 변경 등 구체적인 방안 마련을 위한 검토가 필요하다. 또한 제도적 변경에 앞서 첨단 장비를 통한 안전점검 결과에 대한 확인 및 검증이 필요하므로, 국가차원의 공식적인 연구나 검증 기관 운영 등이 필요하다. 이를 통해 유지관리 분야에 스마트 점검 기술이 도입되면, 터널 등 SOC 시설물의 일상적인 점검이 가능해질 것으로 예상된다. 결과적으로 시설물 상태변화에 의한 안전사고를 미리 인지하고 선제적으로 대응할 수 있는 유지관리 기술이 정착될 수 있을 것으로 기대된다.

In recent years, the service life of major SOC facilities in south korea has exceeded 30 years, and rapid aging is expected within the next 10 years. This has led to a growing recognition of the need for proactive maintenance of these facilities. Consequently, there have been numerous research efforts to introduce smart inspection technologies into maintenance. However, the current system relies primarily on manpower for safety inspections and diagnostics, and on-site surveys rely on visual inspections. Manpower inspections can be time-consuming, and subjective errors may occur during result analysis. In the case of tunnels, there are disadvantages, such as the loss of social overhead capital due to partial closures during inspections. Therefore, institutionalizing smart safety inspections is essential, considering specific measures like using advanced equipment and updating qualifications for experts. Furthermore, it is necessary to verify and validate safety inspection results using advanced equipment before instituting changes. This could be achieved through national-level official research programs and the operation of verification and validation institutions. If smart inspection technology is introduced into maintenance, routine inspections of SOC facilities, such as tunnels, will become feasible. As a result, maintenance technology capable of early detection and proactive response to safety incidents caused by changes in facility conditions is anticipated.
