Abstract

It is expected that the maintenance cost of domestic bridges will increase considerably due to the increase of bridge service time. In response to this situation, the government and relevant ministries are focusing on developing ways to efficiently allocate limited budgets and to rationally select maintenance bridge. In this study, to develop a risk - based bridge maintenance priority decision model, 14 common risk factors causing damage to bridges were extracted and AHP analysis was performed to select 5 important factors. Based on the existing literature review and expert consultation, we derive the evaluation criteria and the impact weights of the selected factors, and based on this, I presented risk based bridge maintenance priority model. Using this model in combination with existing maintenance priority methods will lead to more reasonable bridge maintenance priorities.

국내 교량은 공용 연수의 증가로 인하여 추후 유지관리 비용이 상당히 증가 될 것으로 예상된다. 이에 대응하여 정부와 관련 부처는 한정된 예산을 효율적으로 분배하고, 유지관리 우선순위를 합리적으로 선정할 수 있는 방법 개발에 집중하고 있다. 본 연구는 위험도기반의 유지관리 우선순위 선정 모델을 개발하기 위하여 교량의 파손을 야기하는 일반적인 위험 인자 14개를 선정하고, AHP분석을 수행하여 중요 인자 5개를 선별하였다. 기존 문헌 고찰과 전문가 자문을 통하여 선정된 인자에 대한 평가 기준, 영향도 가중치 등을 도출하였고 이를 활용하여 엑셀시트 기반의 위험도기반 우선순위 선정 기초 모델을 제시하였다. 본 모델을 기존의 유지관리 우선순위 선정 방법과 병행하여 사용한다면 보다 합리적인 교량 유지관리 우선순위를 도출 할 수 있을 것이다.
