Abstract

The purpose of current tunnel maintenance system in South Korea is safety-based maintenance system for accident prevention, So it is difficult to conduct a strategic maintenance. The development of a new maintenance system can lead to effective investment of limited financial and it’s effort is still in progress. In this study, to develop a performance-based assessment method, indexes for assessment are derived taking into account the safety, durability and serviceability. The indexes for performance-based assessment were selected by a literature analysis and a delphi survey. Then the importance among indexes were calculated by the AHP analysis.

기존의 터널 유지관리 체계는 결함 및 손상부위의 보수 또는 설계기준을 충족하기 위한 보강 등 사고예방적인 안전성 중심의 유지관리방식으로 관리되고 있어 효율적이고 전략적인 유지관리를 실시하는데 한계를 보이고 있다. 현재 국가연구를 통해 터널의 성능저하를 예측, 평가하여 한정된 재정을 효율적으로 투자할 수 있도록 성능중심의 유지관리체계로의 전환을 시도하고 있다. 본 연구에서는 터널시설물을 중심으로 기존의 안전중심의 유지관리 체계에서 구조적 안전은 물론이며, 서비스수준 및 내구성능 등의 성능저하를 고려한 터널시설물의 성능중심 평가체계의 개발을 위하여 성능평가를 위한 평가지표를 도출하고자 한다. 성능중심 평가기법 개발을 위한 평가지표는 문헌자료 분석 및 델파이 설문을 통하여 선정하였으며, 평가지표간의 중요도는 AHP 분석을 통해 산정되었다. 본 연구결과는 터널시설물의 성능중심 유지관리 체계에 적용되어 터널의 유지관리 시 합리적인 의사결정을 지원할 수 있을 것으로 판단된다.
