摘要
矮塔斜拉桥受力复杂,施工技术要求高,属于多次超静定结构,矮塔斜拉桥正作为一种新桥型在国内蓬勃发展。文中概述了矮塔斜拉桥的发展趋势,通过对南淝河矮塔斜拉桥的有限元模拟分析,得出在不同的合拢顺序下全桥的应力及挠度的变化情况,并对施工时的体系转换进行控制,优化对结构有利的施工工艺,为同类型桥梁的设计与施工提供参考。
Low Tower Cable-stayed Bridge is stress complex,requires high construction skills,and is a statically indeterminate structure.Recently,Low Tower Cable-stayed Bridges are developing rapidly in China.The paper summarizes the development of Low Tower Cable-stayed Bridges.The construction process of a Low Tower Cable-stayed Bridge is simulated based on finite element method.It can be concluded that the change of the stress and the deflection in the different condition of the closure order control the structure system transformation,which will be instructive to the design and construction of bridges of the same kind.
