Abstract
The tilting-train being operated in pre-existing rail road has a different running mechanism compared to currently operated trains. Therefore, it needs to investigate the evaluation of the track performance, the stability of the tilting-train in operating condition, and the stability of the roadbed. In this study, when the tilting train is operated in the rail joint with the allowable velocity limited by the track performance and the stability of the tilting-train, the settlement of the roadbed has been evaluated by using numerical analysis. The loading on the ground surface generated by the operating tilting-train generates the settlement of the roadbed. The settlement induced by the tilting-train loading has been compared to the allowable settlement and the factor of safety defined by the ratio of the allowable settlement to the settlement generated by the applied loading is evaluated.

요지
기존선에 투입되는 틸팅차량은 기존 차량과는 다른 운행 메커니즘을 가지고 있으므로 안정성을 확보하기 위해서는 궤도부담력 및 주행안정성 검토와 노반의 안정성 검토가 필요하다. 본 연구에서는 레일 이음매 궤도에 대하여 틸팅차량이 궤도부담력과 주행안정성 검토에서 산정된 허용속도로 운행될 경우 발생하는 노반의 침하량을 수치해석을 통해 검토하였다. 틸팅차량 하중에 의해 발생되는 노반의 침하량과 허용침하량을 비교하여 노반의 안정성을 검토하였으며, 허용침하량과 틸팅차량 하중에 의해 발생하는 침하량의 비를 안전율이라 정의하여 안전율을 검토하였다.
핵심용어: 틸팅차량; 레일 이음매; 노반; 침하량; 수치해석
