| Abstract: | The right-branching bridge of Nanjing Yangtze River Tunnel is a self-anchored suspension bridge with single tower and its side-span concrete box girder and main-span steel box girder are connected by the steel-concrete composite segment. The steel-concrete segment used PBL shear key, shear welding nails, prestress and other corresponding measures to overcome the influence on the beam body from different materials, temperature and other factors, making the bridge concrete and steel box girder to form a whole, to meet the needs of structural mechanics. |
