摘要
南京长江隧道工程右汊独塔自锚式悬索桥,边跨混凝土箱梁与主跨钢箱梁通过钢混结合段进行连接,钢混段采取PBL剪力键及抗剪焊钉、预应力等相应措施克服因材质不同、温度等因素对梁体的影响,使全桥混凝土与钢箱梁形成一个整体,满足结构受力需要。
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.
