Abstract

The Korean government amended the Facilities Safety Act in 2018 to establish a performance-based maintenance system. This system is designed to comprehensively evaluate the safety, durability, and usage performance of facilities required to maintain their function in use, and to establish corresponding maintenance plans. However, the current maintenance system of utility tunnels is managed by a safety-oriented evaluation method, which has limitations in conducting performance evaluations that consider durability and usage performance. Therefore, in this study, safety, durability, and usage performance items for utility tunnels were selected using the Delphi method, and the weight of each item was calculated using the entropy weighting method. The results of this study are expected to be used in future performance evaluations of utility tunnels to support rational decision making when establishing maintenance plans.

국내에서는 최근 빈번한 사고를 유발하는 지하시설물의 안전확보 및 효율적 유지관리를 위해 공동구를 포함한 지하시설물을 중점관리 대상 시설로 선정하고 ｢시설물의 안전 및 유지관리에 관한 특별법｣을 개정하여 성능중심의 유지관리체계를 도입하였다. 성능 중심의 유지관리체계는 사용 중인 시설물의 기능을 유지하기 위하여 요구되는 시설물의 안전 ‧ 내구 ‧ 사용성능을 종합적으로 평가하고 그에 따라 유지관리계획을 수립하는 것이다. 그러나 현행 공동구 유지관리체계는 안전성 위주의 평가방식으로 관리되고 있어 내구 ‧ 사용성능이 고려된 종합성능평가를 실시하는 데에는 한계가 있다. 이에 본 연구에서는 델파이 기법을 활용하여 공동구에 대한 안전 ‧ 내구 ‧ 사용성능 항목을 선정하고 엔트로피 가중치 기법을 통해 각 항목들에 대한 가중치를 산정하였다. 향후 공동구 성능평가 시 본 연구에서 도출된 연구결과를 활용한다면 유지관리계획 수립 시 합리적인 의사결정을 지원할 수 있을 것으로 기대된다.
