The “Big Bridge” is under construction in the city of Nanjing over the Yangtze River. It is part of the dedicated passenger high-speed railway line from Beijing to Shanghai and has a total length of approx. 9.3 km. The foreshore bridges consist of 266 individual system girders of the “32 m box girder” type along with individual continuous beams, which are constructed primarily using the free cantilever method. The poor soil conditions in the area made it necessary to use pile foundations with large diameters.
The steel truss arched bridge, which has a total length of 1,615 m, spans the Yangtze River with two central spans of 336 m each. The steel structure is constructed using a cantilever method with temporary rope restraints to brace the segments during assembly. The bridge foundations consist of piles with a diameter of 2.8 m. For the three pillars within the two main span areas, 46 piles, each with a length of 105 m, were constructed.
