아스팔트콘크리트 궤도용 강관형 앵커의 직접 전단 실험

Asphalt concrete track is a type of track systems where sleepers and panels are installed directly on the asphalt concrete trackbed. The track system requires adequate resistance to lateral displacement induced by different types of external forces, such as the longitudinal rail force of the continuous welded rail, traction/braking load, centrifugal force, and lateral force from hunting oscillation. In this paper, the shear strength of a tube-type anchorage device, developed to increase the resistance capacity for the lateral displacement, was calculated through the direct shear test. Based on the shear strength, the installation design of resistance device against track displacement was performed.
