Abstract

Recently, interest for environmental pollution in various fields is on the increase, and the researches on the life cycle assessment of environmental performance assessment method for calculating the environmental loads are currently most performed. It is expected to have a significant influence on the environment, since SOC infrastructures are go through a variety of materials, manufacturing process, however it is judged that researches and measures for environmental pollution is insufficient. In this study, we build the data for 204 of steel bridge designed after 2000 year, and the 100 of bridge which were selected to from obtained results were calculated the environmental loads at the planning stage based on the life cycle assessment. In addition, standard classification systems in work type for steel bridges were established. Based on this, the basic design data and input materials for the bridges are applied to the LCI DB, and the environmental load for required material is evaluated and is shown as Eco-point. Environmental loads obtained from this study, it is judged that can be utilized as a basic data for the process of the life cycle assessment in future steel bridge design.

최근 들어 다양한 분야에서 환경오염에 대한 관심이 높아지고 있으며 환경부하를 산출하는 환경적합성평가방법인 전과정평가에 관한 연구는 현재 많이 진행되고 있다. 그러나 SOC 시설물은 다양한 자재, 공정과정을 거치기 때문에 환경에 많은 영향을 미칠 것으로 예상되나 아직까지는 환경오염에 대한 대책 및 연구가 부족한 것으로 판단된다. 본 연구에서는 2000년 이후 설계된 204개 강교에 대한 데이터를 구축하였으며, 그 중 100개 교량을 대상으로 기획단계에서의 전과정평가를 실시하여 환경부하량을 산출하였다. 또한 강교에 대한 표준 공종 분류체계를 정립하였고, 이를 바탕으로 교량의 기본 설계 자료와 투입자재에 LCI DB를 적용하여 소요자재별 환경부하량을 산정하고 이를 Eco-point 값으로 나타내었다. 본 연구에서 도출된 환경부하량은 향후 강교의 설계에서 전과정평가 과정에 대한 기초자료로서 활용될 수 있을 것으로 판단된다.
