Noise and Vibration of Resiliently Supported Track Slabs [PDF]
The Journal of the Acoustical Society of America, 1973 In this paper the dynamic response, vibration isolation, and sound radiation of a resiliently supported track slab are analyzed. An analytical model is investigated which views railroad rails as beams fastened elastically to a slab which is resiliently mounted to a substructure. The slab is assumed to be a plate of finite width and infinite length. The

Quality of Slab Track Construction – Track Alignment Design and Track Geometry [PDF]
Civil and Environmental Engineering, 2015 Abstract The slab track superstructure design (without ballast) is a perspective construction especially for building tunnels and bridges in the modernized sections of railway tracks in Slovakia. Monitoring of the structure described in this article is focused on the transition areas between standard structure with ballast and slab ...
