초록
본 논문은 국내·외 (미국, 영국, 일본, 한국)의 교량유지관리활동을 비교하였다. 교량은 물류 및 교통망에 있어 매우 중요한 역할을 하고 있다. 제한된 예산으로 시민에게 적절한 수준의 서비스를 제공하기 위해서는 효율적인 교량 유지관리 활동 (예, 점검 및 보수·보강)이 이루어져야만 한다. 1980년대 후반 급속한 경제 성장은 국내 사회기반 시설 증가로 이어졌고 교량의 개소수 또한 급속도로 증가 하게 하였다. 교량 증가와 함께 노후화 또한 최근 빠르게 진행되고 있으며 이러한 교량 노후화 속도는 교량 유지관리를 담당하고 있는 관리주체에게는 상당한 부담이 되고 있다. 다행이 이러한 과정을 이미 경험하고 있는 해외국가의 체계적이고 종합적인 교량 유지관리 체계는 국내 유지관리 체계에 상당한 시사점을 줄 수 있을 것이라 판단하다. 따라서, 본 연구의 목적은 교량유지관리 선진국 (예, 미국, 영국, 일본)에서 시행되고 있는 교량 유지관리활동을 비교 분석하여 국내 유지관리에 시사하는 점을 분석하였다.
Abstract
This paper compared bridge maintenance in United Stated, United Kingdom, Japan, and Korea. Bridges play an essential role in transportation network and in the economic production process. To provide a desirable level of service to the public within limited budgets, it is required to provide effective bridge maintenance activities (e.g. inspection and repair/rehabilitation) at acceptable level of bridge service. A number of bridges are expected to age rapidly in Korea, which will be the excess burden of government. Since several countries have experienced a number of deteriorated bridges because of aging, the countries aforementioned in this study have already developed comprehensive bridge maintenance programs such as inspection practice and repair/rehabilitation techniques. Therefore, the goal of this paper is to synthesize and to compare useful knowledge on bridge maintenance and bridge crack repair/restoration of deteriorated concrete bridge in the four countries. Finally, recommendations that will serve as guidance to transportation agencies for potential enhancements to bridge maintenance and bridge repairs are presented.
