초록
산악지형이 많은 우리나라는 1970년대 이후 급속한 경제발전과 함께 수많은 터널이 건설되어 왔으나 터널의 필요성에 대한 인식에 비해 터널의 유지관리에 대한 관심은 부족한 상태이다. 국내 터널의 유지관리체계는 점검 후 이상이 발견 되었을 때 대처하는 대응적 유지관리 체계로서, 앞으로 노후화 터널이 급격히 증가하면서 각 기관들의 제한된 예산의 범위와 인력으로는 일일이 대응하기 어려워질 것이다. 따라서 본 연구에서는 터널의 유지관리를 전략적이고 장기적인 관점에서의 예방적인 관리 체계로 변환시키기 위한 LCCA(Life Cycle Cost Analysis)기반 터널 자산관리 시스템의 필요성과 개발방향에 대한 프레임웍을 제시하고자 한다. 국외 선진국의 사회기반시설물에 대한 자산관리 수행사례를 살펴보고 국내 터널관리에서의 자산관리기법의 필요성을 분석하였다. 또한, 터널 자산관리에서 경제적, 공학적의 정량적 의사결정 기법인 LCCA 모델을 적용하여 자산관리모델이 개발되기 위한 구체적인 발전방향을 제시하고 이를 시스템화하기 위한 연구개발 프레임웍을 설계하였다.
Abstract
As many parts of Korea are mountainous, many tunnels have been constructed to be in step with rapid economic development since 1970’s. However, the interest on maintenance of tunnels is far less than the awareness of need for tunnels. As the tunnel maintenance system is the responsive maintenance system which responds to the problems found during the inspection, it will be very difficult to respond to each problem with the limited budget and manpower of the government agencies when the number of aged tunnels rapidly increase in the future. As such, this study presents the need for the LCCA (Life Cycle Cost Analysis) based tunnel asset management system to transform the tunnel maintenance to a preventive management system in a strategic and long-term viewpoint and proposes the framework for development direction. It observed the asset management implementation cases of social infrastructure in other countries and analyzed the need for asset management technique to manage the tunnels in Korea. Moreover, it applied the LCCA model, which is the economic and engineering quantitative decision making technique, for tunnel asset management to present the concrete direction for development of an asset management model and designed the R&D framework to systemize it.
