Abstract:The fast road in the east section of South Ring Road (Heqing Road ~ East Outer Ring Road) is an important part of the express way network in the downtown area of Ningbo, which forms a "fast ring road" in the downtown area, and mainly undertakes the long-distance traffic function of city in order to connect various functional areas of city. The project is connected with the elevated "diving platform" reserved for Dongyuan Interchange in the west, and to the east is connected with the current cross-railway bridge (the landing section is uplifted and reconstructed), and after crossing the planned Shengmei Road, it is connected with the East Outer Ring Road-South Ring Road Interchange. The newly built and reconstructed bridges are about 3.5 km long. The engineering construction land is tight, the conditions are harsh, the underground pipelines are complex, the surrounding buildings are many, and the traffic pressure during the construction period is heavy. Through the in-depth research and refined design, combined with the field practices and construction schemes, the reasonable bridge-type structures are selected, and the existing structures are fully utilized, which make the bridge design safe, reasonable, economical and applicable.
