Box girder design and erection

The superstructure of the extradosed bridge consists of two parallel box sections which are connected by a diaphgragm at the piers as well as through a continuous deck slab. The webs of box sections are designed as butterfly webs made of precast high-strength (80 MPa) fiber-reinforced precast concrete elements, 2.900 meters wide and 15 cm thick, which connect to the upper and bottom flanges of the box through dowels. They are also prestressed diagonally. The box girders were erected by cantilevering out from the piers first laterally to achieve the full width of 24 meters on a 5.5 meter diameter pier and then longitudinally in block lengths of 6.0 meters using a launching gantry.

Pier design and erection

The piers are made of single-shaft hollow circular section with a diameter of 5.00 m (P3) or 5.500 m (P1, P2, P4). The shortest pier, P1 is 54.200 meters tall while the highest, P3 and located in the middle of the river, is 81.200 meters high. Pier P4 is supported on a rectangular flat footing while the other piers are supported by circular caisson foundations. The piers were erected using the SPER method using half-precast reinforced concrete elements 2.0 meters high with embedded hoops and ties. Two of semi-cylindrical elements were used to make up the hollow circular section of the piers. They are pre-assembled and then lifted onto the already erected part of the pier. This method reduces the amount of formwork necessary on-site considerably, as the outer and inner pannels of the precast elements serve as formwork for most of the perimeter. Formwork is only necessary where the elements are joined in-situ. The hollow spaces between the outer and inner panels are also filled in.
