Abstract

This paper is a maintenance system for bridge represented by Class 3 and other than by law bridges. Domestic bridge are divided into Class 1 & 2 bridges and Class 3 & other than by law bridges. The number of type 3 and other than by law bridges is very large. But, it is considered to be of relatively low importance compared to Class 1 & 2 Bridge Bridge. So, in this paper is propose a maintenance system and procedure for small & medium-sized bridges. However, because the number of small & medium-sized bridges is large, it is not possible to evaluate the performance of all bridges like Class 1 & 2 bridge. The reason is the lack of manpower and budget. Based on the Risk Matrix method, a maintenance procedure was created to select the bridge for which performance evaluation should be performed first. For this purpose, basic information of the bridge is used. And, the developed maintenance procedures were applied to the bridges in actual use.

본 논문은 3종 및 법정 외 교량인 중소규모 교량에 대한 유지관리 체계를 수립하여 제안하는데 그 목적을 두고 있다. 국내 교량은 1, 2종 교량과 3종 및 법정 외 교량으로 구분된다. 3종 및 법정외 교량의 개소수는 많으나 1, 2종 교량에 비해 상대적으로 중요도가 낮은 것으로 판단된다. 따라서 본 논문에서는 이러한 중소규모 교량에 대한 유지관리 시나리오 체계를 수립하고자 한다. 하지만 중소규모 교량의 경우 그 개소수가 많아 1, 2종 교량과 같이 모든 교량에 대해 성능평가를 실시하는데 인력과 예산의 문제가 있다. 이에 따라 본 연구는 리스크 매트릭스 기법을 기반으로 교량의 기본적인 현황정보를 이용하여 현재 성능평가가 우선적으로 수행되어야할 교량을 선정하기 위한 기법을 개발하였으며, 개발된 기법에 대하여 실제 공용중인 교량을 대상으로 적용하였다.
