| 摘 要： | 运用现代有限元方法分析了某斜拉桥索梁锚固区局部应力的分布规律及索力的扩散规律。结果表明,索力引起主梁顶板内局部较大的横桥向拉应力,与锚块固结的横隔板和箱梁腹板则传递和承受了大部分的垂直索力分量。

| Abstract: | The local stress distribution of cable-girder anchorage zone of a cable-stayed bridge and the transfer of cable force are analyzed by modern finite element method.The result shows that huge cable forces cause large transverse tensile stress in the deck,and the vertical component of cable forces is transferred by the diaphragms and the webs of box girder fixed with the anchor zone. |
