Introduction of Jinan Yellow River Railway Bridge for Century Passenger Dedicated Line.

On the south side of Jinan Yellow River Highway and Railway Bridge, Shijike Passenger Dedicated Line is located near Fujiazhuang, Huashan, Jinan City. The upper part of the bridge is an expressway with six lanes in both directions. The lower part is a continuous steel truss beam, with a length of 1.792km and a main span of 1.80m, four-lane railway, Shijiazhuang-Jinan passenger dedicated line, and ordinary-speed double line.

Building structure

The railway under the Yellow River highway-railway dual-purpose bridge of Shijike Passenger Dedicated Line adopts 6-32m prestressed concrete simply supported beam,1.22m simply supported steel truss beam, 7-52m simply supported prestressed concrete beam, 796m rigid suspension stiffened continuous steel truss beam and 9-32m simply supported prestressed concrete beam.

The superstructure of the Yellow River Highway-Railway Bridge adopts prestressed concrete continuous beams from 2m to 99m, 122m simply supported steel truss beams, 378m prestressed concrete continuous beams, 796m prestressed steel truss beams, 1m to 132m prestressed concrete continuous beams and 165m prestressed concrete continuous beams. Rigid suspended cable stiffened continuous steel truss girder with span of 796m spans the main channel of the Yellow River, and simply supported steel truss girder with span of1m ~122m spans the north dike of the Yellow River. It is reported that the upper part of the main bridge is a two-way six-lane urban expressway and the lower part is a two-way four-line railway.

Jinan Yellow River Highway-Railway Dual-purpose Bridge of Shijike Passenger Dedicated Line is a rigid suspension stiffening continuous steel truss bridge, and its structural form is the first time on domestic railway bridges. Jinan Yellow River Highway-Railway Bridge of Shijike Passenger Dedicated Line is novel in type, with a large amount of work, and the technical difficulty of construction is rare for similar bridges in China. It has the technical difficulties of long pile foundation, various pier combinations, complex structural stress and high linear control accuracy, and will become an important economic link connecting Jinan urban and suburban areas after completion.

meaning

The construction of Jinan Yellow River Highway-Railway Dual-purpose Bridge on Shijike Passenger Dedicated Line means that the Shijike Passenger Dedicated Line, which was completed four years later, not only provides the residents in eastern Jinan with the opportunity to cross the Yellow River by emu, but also allows them to cross the Yellow River by car, bus or even on foot. This not only provides a convenient passage for Jinan to cross the Yellow River in the east, but also writes a new history for Jinan to cross the Yellow River in the north, because in the past, it was the first time that Jinan used the highway-railway bridge. It indicates that the largest bridge across the Yellow River in China will enter the substantive construction stage. Jinan Yellow River Highway-Railway Bridge of Shijike Passenger Dedicated Line was built by China Railway Fourth Bureau. Upon completion, it will become an important transportation hub of Shijike Passenger Dedicated Line and another important economic link to help Jinan's "North Span" development.
