아스팔트 궤도노반용 콘크리트 슬래브 직결궤도의 전단키 설계 및 성능평가

The Concrete slab on asphalt trackbed experiences the misalignment phenomenon from the original place caused by the curved track, the displacement from temperature difference between the top and bottom of the slab, and the wind pressure exerted on the train. In order to suppress this phenomenon, the shear key was installed between two. In this study, a comparison of experiment and analysis on two different shear keys was utilized to interpret the actual model result analysis.
