Abstract

In the case of CWR (Continuous welded rail) located on the railway bridge, the CWR has additional axial force due to interaction of bridge and track. Therefore, the CWR tracks located on the bridge have to secure the safety of running train and CWR track through mitigating influence for interaction of bridge and track. The railway design guide in Korea (KR C-08080) provides a certain value for property of longitudinal friction behavior of rail fastening system that is major parameter of interaction behavior by applying European codes. However, in order to apply to domestic railway, it is necessary to review property characteristics of the rail fastening system in actual use. In this paper, the experiment for longitudinal friction behavior of rail fastener applied to concrete track on the railway bridge in Korea was carried out, and statistical characteristic for property of the rail fastener was analyzed from the result of the experiment.

장대레일 궤도가 철도교량 상에 위치하는 경우, 교량과 궤도의 상호작용에 의해 레일에 발생하는 축력분포가 복잡해지며 부가축력이 발생하여 토노반상 장대레일에 비해 큰 축력이 레일에 발생된다. 이로 인해 교량상에 부설되는 궤도는 교량과의 상호작용 영향을 최소화하여 궤도와 주행열차의 안전성을 추가로 확보하여야 한다. 국내 철도설계지침 및 편람 KRC-08080(궤도-교량 종방향 상호작용 해석)에서는 상호작용의 주요 변수인 레일체결장치의 종방향 저항(마찰거동) 물성치가 유럽기준을 적용하여 특정 수치로 규정되어 있으나, 국내 철도에 적용하기 위해서는 실제 사용되는 체결장치의 성능 특성을 반영한 검토가 필요하다. 본 논문에서는 국내 교량상 콘크리트 궤도에 적용되는 레일체결장치의 마찰거동 실험을 수행하였으며, 이로부터 체결장치의 물성치에 대한 통계적 특성을 분석하였다.
