The Repair and Reinforcement of Tummel using The Carbon Fiber Sheet

탄소섬유시트를 활용한 터널의 보수.보강

Most of existing tunnels in Korea have structural and material defects, such as lack of the thickness in the crown and presence of an opening behind thie lining as a result of its construction. In Japan, it is said that carbon fiver sheet is very attractive for the upgrading damaged tunnel due to its good tensile strength, handability and resistance to corrosion. This report is the summary of the applicability of continous carbon fiber sheet for a repair and reiforcement of existing tummel located in Masan. It is the aim of this study to analyze the site data related to consturcion method used carbon fiber sheet.
