Abstract

Infrastructure which mandatory in human life causes large environmental loads when they are being installed and maintained. Especially, maintenance is performed over a long period of time. Also, there is a limit to suggest a reliable estimated value because environmental loads are changed according to methods of maintenance and periods. In this study, we developed a Environmental Load Estimating Model to evaluate value and plan as soon as possible in the Early Design Phases while maintaining a tunnel. To estimate environmental loads by using brief design information, we analyze a calculation methodology of environmental loads in maintenance phases. Furthermore, we apply periods of maintenance work and maintenance factors considered a characteristic of long-term maintenance. Finally, a main purpose is that this program makes all users estimate environmental loads in maintenance phases easily and quickly. Accordingly, it is considered that the Environmental Load Estimating Model offer assistance to eco-friendly maintenance of the road and tunnel construction.

인간이 절대적으로 필요한 사회기반시설은 설치 및 유지관리 시 큰 환경부하를 발생한다. 특히, 유지관리는 장기간에 걸쳐 수행되며 보수방법 및 주기에 따라 환경부하가 달라지기 때문에 신뢰할 수 있는 추정 값을 제시하는데 한계가 있다. 이에 본 연구에서는 터널을 유지관리 할 때 발생하는 환경부하를 기획 또는 설계초기단계에서 신속하게 평가할 수 있도록 환경부하 추정모델을 개발하였다. 간략한 설계 자료만으로도 환경부하를 추정할 수 있는 모델개발을 위하여, 유지관리 단계에서의 환경부하 산정 방법론을 분석하고, 장기적인 유지관리의 특성을 고려한 보수주기와 보수율을 적용하였다. 최종적으로 모든 사용자들이 유지관리단계의 환경부하량을 편리하고 신속하게 추정할 수 있는 평가모델을 개발하는 것이 본 연구의 목표이며, 이를 통해서 도로 및 터널사업의 친환경적인 유지관리에 도움을 줄 수 있을 것으로 판단된다.
