Abstract

In this study, the reference values for the internal forces of the rail supports caused by a wheel load, a unit vertical displacement, a unit end rotation in examination of the serviceability of concrete slab track bridge were obtained. In analysis, the analysis models of which the rail was continuously and discretely supported by elastic springs were used. The internal forces of the rail supports from the analysis were compared with the results provided in the DS 804 regulations and agreed with well. In addition, the effects of the space between the rail supports and the stiffness of fastener on the internal forces of the rail supports were investigated.

본 연구에서는 콘크리트 슬래브 궤도를 가지는 교량의 사용성 검토에 있어 단위 축하중, 단위 수직 단차, 단위 회전에 의해 발생되는 레일 지지점의 작용력에 대한 기준 값을 구하였다. 해석방법에 있어서는 레일이 탄성 스프링에 의해 연속적으로 지지되는 모델과 이산적으로 지지되는 모델이 이용되었다. 해석결과 얻어진 레일 지지점에서의 작용력은 콘크리트 궤도의 사용성 검토에서 참조되고 있는 DS 804 기준에 제시된 값과 비교되였으며, 그 결과는 잘 일치하였다. 또한, 레일 지지점의 간격과 체결장치의 강성이 레일 지지점에서의 작용력에 미치는 영향을 분석하였다.
