Stability of CWR track on the High-Speed Railway Bridges considering Braking and Accelerating Forces
- 발행 : 2004.10.01
초록
In this paper, the main factors affect on the longitudinal rail force are discussed. Considering rail-bridge interaction, analytical and experimental evaluation of track behavior has been achieved. It is concluded that the horizontal ballast strength, the expansion length of the bridge span, and the stiffness of the bridge sub-structure are the significant parameters affecting the stability of the continuous welded rail (CWR) track. And, it is suggested that the ballast resistance forces should be maintained to ensure the track stability during the service.
