Abstract

Domestically, technical condition evaluation for breakwaters has been conducted through safety checks and safety diagnosis. If necessary, maintenance for the facility is conducted. However, in recent years, the need for infrastructure management has been increasing from a life-cycle-cost perspective. For these reasons, the "Sustainable Infrastructure Management Basic Act" was enacted. Previously, only the technical part of the breakwaters was evaluated. However, based on the act, comprehensive management of breakwaters will be possible through performance improvement by adding economic and political evaluations. In this study, evaluation factors and evaluation methods were developed for a breakwater rehabilitation project. The purpose of this study is to present a development direction, items, and methods for the evaluation of breakwater performance improvement to be applied in future practice. This study reviews the concept of maintenance and performance improvement, the literature related to performance improvement, and the project type for the common standard of performance improvement. Evaluation items and evaluation methods for breakwater rehabilitation are suggested to be reviewed by experts. The methodology suggested in this study could be used for preventive maintenance and to reduce accidents.

국내에서 항만의 방파제는 안전점검 및 안전진단을 통해 기술적 상태평가를 수행하고, 필요 시 해당 시설물에 대해 유지관리를 수행한다. 그러나 최근 생애주기비용(Life Cycle Cost, LCC) 측면에서 기반시설에 대한 관리의 필요성이 증가함에 따라 「지속가능한 기반시설 관리 기본법」이 제정되고, 방파제의 기술적 부분만 평가했던 기존 평가방식에 경제성 평가 및 정책성 평가가 추가되어 성능개선을 통해 방파제에 대한 종합적인 관리가 가능해질 것으로 예측하고 있다. 이러한 이유로 본 연구는 「지속가능한 기반시설 관리 기본법」에서 규정하고 있는 총공사비 500억 미만의 방파제 성능개선사업을 대상으로 성능개선사업의 세부평가항목 및 방법 등을 개발하여 평가방안을 제시하고, 향후 실무에 적용될 성능개선 평가를 위한 방파제 성능개선 평가항목 및 평가방법의 개발 방향을 제시하는 것을 목적으로 연구를 수행하였다. 본 연구는 유지관리 및 성능개선의 개념 검토, 성능개선 관련 문헌조사, 성능개선 공통기준 사업유형 검토, 방파제 성능개선 평가항목 및 평가방법(안) 도출, 전문가 검토 등의 순서로 수행하였으며, 도출한 방파제 성능개선에 대한 평가방안은 지금까지 기술적 상태평가에 국한된 유지관리 업무에 성능개선을 적용한 구체적인 평가방법을 제시한 것으로 시설물의 선제적 관리 및 안전사고 예방에 활용 가능할 것으로 기대된다.
