The design of the Unstrut Viaduct
The Unstrut Viaduct is being constructed based on state-of-the-art engineering skills. The track runs on a series of jointless, bearingless reinforced concrete girders. Special solutions at the ends of these girders allow for temperature deformation.
Facts and figures
|Structure type:||Integral prestressed concrete hollow box bridge consisting of six continuous girders with four arches and slender supports|
In the middle of the four 580-metre girders, the structure is supported by large reinforced concrete arches in the shape of an inverted V with a span of 108 metres. The arches are linked to the girders at the top. Transversely, the arches split at each end into two legs that are spread apart. This gives the arches great stability in all directions.
In addition to these elegant arches, there are 41 equally slender supports with spacing of 58 metres. The abutments, supports and arches have deep foundations in the Buntsandstein. The foundations are based mostly on large-bore concrete piles that go down to depths of up to 40 metres.
