- Abstract
Floating-slab trackbeds for the reduction of vibrations from railway lines can be implemented using three different forms of bearing application: surface bearings, strip bearings or single bearing pads. On the basis of previous findings, surface bearings and bearing pads have shown themselves to be particularly successful. In order to minimize costs strip bearing applications have also been developed [1]. In the course of the new development plans of the Austrian Federal Railway rail network an abundance of mass-spring-systems are being designed. It should therefore be established, by means of a test track, what advantages strip bearings offers compared to surface bearings and whether using strip bearings the gap between single bearing pads and area bearings can be filled. To this end a test track was set up in the area of the Birgltunnel in the course of the double track extension of the Austrian Federal Railway's Tauern line. The double track tunnel was fitted out with a surface bearing based floating slab for one track and with a strip bearing based floating slab for the second track. Equal mass distribution and natural frequencies for both floating slab types were defined. An extensive measurement based investigation followed, the results of which are going to be presented. The measurements performed dealt with vibration insulation and ground borne noise insulation, with the systems' natural frequencies as well as with the settlement behaviour under loading. Furthermore the whole civil engineering process was documented and evaluated in detail, in order to gain an overview of the application of strip loading mass-spring systems.
