Abstract

In this study, a basic research was conducted to establish a maintenance plan considering the environmental factors and deterioration characteristics of port facilities. The precise safety diagnosis reports for Incheon and Busan port facilities were referenced to examine the extent of deterioration and damage. The relationship with the degradation environmental assessment presented in the current guidelines was also analyzed. The analysis of the damage level of Incheon and Busan port facilities revealed that Incheon Port exhibited approximately three times higher damage rate compared to Busan Port. In the case of Incheon Port, reinforcement corrosion and external damage showed similar proportions, while in Busan Port, reinforcement corrosion had a higher proportion compared to external damage. On the other hand, when comparing with the degradation environmental assessment presented in the guidelines, it was found that there were some limitations in performing quantitative evaluation based on the guidelines for assessing port facilities. Therefore, an analysis based on tidal range was conducted by referring to existing literature. The analysis of tidal range in Incheon and Busan regions showed that Incheon had approximately five times higher difference compared to Busan. It is considered that this can be utilized as a differentiated item from existing degradation environmental assessment criteria.

본 연구에서는 항만시설물의 환경적인 요인과 열화 특성을 고려한 유지관리 방안을 수립하기 위한 기초연구로서 인천 및 부산 항만시설물을 대상으로 점검 보고서를 참고하여 열화 및 손상정도를 검토하였으며 현재 지침에서 제시하고 있는 열화환경평가와의 관계를 분석하였다. 인천 및 부산 항만시설물의 손상 정도를 분석한 결과 인천항이 부산항보다 약 3배 정도 높은 손상률을 나타내었으며 인천항의 경우 철근부식 손상과 외부요인 손상의 비율이 유사하게 나타났으며, 부산항의 경우 철근부식 손상이 외부요인 손상의 비율보다 높게 나타났다. 한편 지침에서 제시하고 있는 열화환경 평가와 비교한 결과 지침에서 제시하고 있는 열화환경 평가를 바탕으로 항만시설물을 평가할 경우 정량적 평가를 수행함에 다소 한계가 있는 것으로 확인되었으며 기존 문헌을 참고하여 조수간만의 차를 바탕으로 분석을 수행하였다. 인천 및 부산 지역에 대한 조수간만의 차를 분석한 결과 인천이 부산보다 약 5배 높은 조수간만의 차를 나타내었으며 이는 기존 열화환경 평가 항목보다 지역 및 해역에 대해 정량적으로 열화환경을 평가할 수 있는 항목이 될 수 있을 것으로 판단된다.
