文章介绍了近年来悬索桥的发展,并介绍了国内外三塔悬索桥的建设情况。悬索桥具有较大的几何非线性。在某三塔悬索桥的施工技术研究过程中,运用ANSYS软件的静态分析功能,采用迭代分析的方法,得到了三塔悬索桥的成桥状态和空缆状态的线型,同时研究了三塔悬索桥在最不利活载作用下中跨的挠度、主缆在塔顶的抗滑安全性、并分析了加劲梁安装的顺序以及所需水平牵引力的大小。
The paper introduces the development of suspension bridges in recent years and introduces the construction of suspension towers at home and abroad. Suspension bridge has a large geometric nonlinearity. In the process of construction technology research on a three-tower suspension bridge, using the static analysis function of ANSYS software, using the method of iterative analysis, the line shape of the three-tower suspension bridge and the status of the aerial cable were obtained. At the same time, The deflection of middle span under the most unfavorable live load, the anti-skid safety of the main cable at the tower top, and the order of the stiffening girder installation and the required horizontal traction force.
