Pfaffenbergbrücke (case study)

The Pfaffenberg Bridge from 1971 is a reinforced concrete arch bridge and is located on the southern ramp of the Tauern Railway on the Schwarzach / St. Veit - Spittal / Drau route. The bridge object transfers two tracks with a ballasted superstructure. Both in the area of the bridge and on the free stretch, the ballast bed height is 45.0 cm. The bridge construction has a total length of 377.0 m.

Object analysis

Through the targeted arrangement of sensors and measuring instruments, air, rail and structure temperatures, relative longitudinal displacements of the structure and relevant deformation parameters of the rails (expansion and compression) were measured and documented as part of a continuous measurement program.

Other

Object state

The Pfaffenberg Bridge was equipped with measuring technology in 1993 to record the interaction effect. In the case of the measuring device, the focus was correspondingly on the measurement of the air, rail and structure temperature, on the recording of the expansion behavior of the rail and on the recording of the structure and rail longitudinal displacements. Track 1 (track on the mountain side) was chosen as the measuring track and equipped with strain gauges and temperature sensors. The strain gauges were applied approximately in the neutral axis of the rail.
