摘要
介绍大跨度钢箱梁斜拉桥索梁锚固结构的 4种常见连接型式 :锚箱式连接、耳板式连接、锚管式连接与锚拉板连接。结合具体工程实例 ,对上述 4种索梁锚固结构进行了静载试验和理论分析 ,详细比较了 4种锚固结构的传力机理、应力分布、应力集中现象 ,以及改善应力分布、减小应力集中现象的一些措施 ,得到一些有益的结论 。
Several typical models of cable-girder anchorage for long-span ca ble-stayed bridges with steel box girder, such as anchor-box, auricular anchor plate, anchor-pipe, tensile anchor plate, are described firstly. Then, based o n the static test and theoretical analysis of the several typical cable-girder anchorages above, the mechanic behavior, stress distribution and stress concentr ation of anchorage zone are studied and compared. The measures to reform stress distribution and to reduce stress concentration are discussed. Some useful concl usion is obtained, and it is beneficial to the design of bridges.
