| Abstract: | North Beicheng river bridge is under a span of 80.6m CFST arch,which is located on the S233 provincial highway（Gaoyou Sangduo to liangdu Port Section）.It is constructed with rigid tie beam for 1.4m × 1.8m pre-stressed box girder by cast-in-situ stent.The bridge meets big construction difficulties due to the underearth conditions and shipping. After the program selection, steel-arch is adopted by integral lifting of simple support, and it has achieved remarkable economic benefits. |
