Abstract

Function and performance degradation in tunnel structure can cause road’s function loss, proactive maintenance is needed to prevent the initial damage from progressing to intensified damage. Inspection and diagnosis are implemented in accordance with regulations, but it does not fully reflect maintenance processes such as inspection and diagnosis, planning rehabilitation and carrying out. It was carried out for 5,540 cases inspection and diagnosis result in 1,728 tunnels was analyzed to suggest rational maintenance plan in this study.

터널구조물의 기능 및 성능저하는 도로의 기능상실 등을 유발할 수 있으므로 초기 손상이 심화된 손상으로 진전되지 않도록 선제적 유지관리가 필요하다. 이에 관련 법령에 따라 정기적인 점검/진단이 시행되고 있으나, 점검/진단, 보수/보강 계획 수립 및 실시 등 일련의 과정을 충분히 반영하지 못하고 있다. 따라서 본 연구에서는 도로터널 1,728개소에 대해 시행한 5,540건의 정밀안전점검, 정밀안전진단 사례에 대한 조사/분석을 통하여 합리적인 유지관리 개선 방안을 제시하였다.
