Abstract

With the enforcement of the infrastructure management act, the importance of utility tunnels that jointly accommodate life-lines such as electricity, communication, water supply, and heating facilities has increased. The currently applied utility tunnel maintenance system is managed in an accident-preventive safety-based evaluation method. However, this evaluation method has limitations in effective maintenance. In this study, performance evaluation items were derived through the Delphi method to suggest a criterion for quantitatively evaluating the performance of utility tunnels, and the weights for each item were calculated through the Analytic Hierarchy Process (AHP) method. In the future, it is judged that a more reasonable performance evaluation standard of utility tunnel can be prepared if modifications and supplements are made through field application.

최근 기반시설관리법('20.10) 시행으로 전기, 통신, 상수도, 난방 시설과 같은 필수적인 라이프라인(Life-Line)을 공동으로 수용하는 공동구의 중요성이 높아진 실정이다. 현행 공동구 유지관리 체계는 사고예방적인 안전성 위주의 평가방식으로 관리되고 있어 효율적인 유지관리를 실시하는데 한계가 있다. 이에 본 연구에서는 공동구 시설물에 대한 성능을 정량적으로 평가하기 위한 기준을 제안하기 위해 델파이 기법을 통해 성능평가 항목이 도출되었고, 계층화 분석법(AHP)기법을 통해 각 항목들에 대한 가중치가 산정되었다. 향후, 현장적용을 통해 수정 및 보완을 한다면 보다 합리적인 공동구 성능평가 기준이 마련될 수 있을 것으로 판단된다.
