초록

교량은 경제 및 사회적 활동에 토대가 되는 핵심적인 사회기반시설이다. 우리나라의 교량은 70년대 경제발전과 함께 건설되기 시작하여 80~90년대에 집중적으로 건설되었다. 최근, 공용년수가 30년을 초과하는 교량의 수가 증가하고 있어서 교량의 안전을 확보하기 위해서는 지속적인 유지관리가 필요하다. 특히, 교량 노후화에 대응하기 위하여 ICT 기술을 활용한 유지관리, 예방적 유지관리, 생애주기 비용 절감, 교량 장수명화와 같은 기술 개발 연구들이 활발히 추진되고 있다. 본 논문은 교량의 내하성능 추정 모델 개발 연구의 일환으로 교량의 안전성 평가 자료에 기초한 상관관계 분석 결과를 제시한다. 분석 결과를 통해, 교량의 내하성능과 상관성이 높은 지표를 도출하였다.

Bridges are a key infrastructure that underpins economic and social activities. In Korea, bridges began to be built with economic development in the 1970s and were built intensively in the 1980s and 1990s. In recent years, as the number of bridges with a service life of more than 30 years is increasing, continuous maintenance is required to ensure the safety of the bridges. In particular, in order to cope with the aging of bridges, research on technology development such as maintenance using ICT technology, preventive maintenance, life cycle cost reduction, and long life bridge is being actively promoted. This paper presents the results of correlation analysis based on the safety evaluation data of bridges as part of the research on the development of a model for estimating load-carrying capacity of bridges. As a analysis result, indicators highly correlated with the load-carrying capacity of the bridge was derived.
