Abstract

Infrastructure plays a crucial role in the industrial development and economic growth of a nation. However, recently, domestic infrastructure has been causing not only safety risks due to aging but also social and economic inefficiencies, increasing the need for maintenance. In particular, the deterioration rate of bridges is serious, so application of appropriate repair and rehabilitation methods and estimation of its quantity are required. In this study, frequently applied repair methods for bridges using data from the Facility Integrated Management System (FMS) were identified. the empirical correlation between damage volume and the repair volume was analyzed using Bridge Management System (BMS) data. The result of the analysis showed that the ratio of the repair volume to the damage volume was 1.0. The guideline, on the other hand, suggest 1.5 the ratio of the repair volume to the damage volume. Although the guidelines differently present more conservative figures considering safety, this study is significant in that it presents a practical ratio through data analysis results. This results can be used to develop a model that can calculate the amount of repair and rehabilitation of various facilities in the future.

인프라는 국가의 산업 발전과 경제 성장에 주요한 역할을 하고 있다. 그러나 최근 국내 인프라는 노후화로 인해 안전사고의 위험 뿐만 아니라 사회·경제적 비효율성을 야기하고 있어 유지관리의 필요성이 커지고 있다. 특히 교량의 노후화 비율이 심각해 적절한 보수보강 공법과 물량 산출이 필요하다. 본 연구에서는 시설물통합정보관리시스템(FMS) 데이터 중 교량에서 빈번하게 적용되는 보수공법을 도출하였고 이를 바탕으로 손상·결함 대비 유지보수공법 물량 간의 상관관계를 파악하였다. 교량통합관리시스템(BMS) 데이터를 활용하여 교량의 손상과 유지보수공법의 물량 간의 경험적인 상관관계를 분석하였다. 분석결과 보수물량과 손상물량의 비율은 1.0으로 나타났으며, 세부지침에서 제시하고 있는 균열률 및 손상면적률을 산정하는 방식은 손상물량의 1.5배를 권고하고 있어 차이를 보이고 있었다. 세부지침에서는 안전을 고려하여 보수적인 수치를 제시하고 있지만 데이터 분석 결과를 통해 실무적인 비율을 제시하였다는 점에서 의의가 있으며, 향후 다양한 시설물의 보수보강 물량을 산정할 수 있는 모델 개발에 활용할 수 있을 것으로 기대된다.
