| 摘 要： | 以恩施州平地坝转体拱桥为背景，以处于脱离支架状态的半跨转动体系为分析对象，运用有限元软件ANSYS建立了空间有限元分析模型，对结构进行静力分析，从拱肋线形，拉索索力，关键部位应力及整体稳定安全系数几个方面对结构的受力性能进行了研究。

| Abstract: | Basing on the Ping di-ba turning arch bridge,when the half-span turning system breaks away the brackets,by using the finite element software ANSYS,the text analyzes mechanical states from several facets,such as elevations of ribs,cable force,key section stress and global stability safe factor.According to the static analysis,the thesis provides some useful instructional gist for the same type bridges' structure designs,construction and inspection. |
