摘要: 针对主跨460 m的预应力钢筋砼斜拉桥一重庆奉节长江大桥,运用有限元系统ANSYS分析施工及成桥状态 下,线性和非线性因素对整体稳定性的影响,并根据ANSYS计算所得参数对大桥稳定性进行评价.

关键词: 斜拉桥, 有限元, 几何非线性, 整体稳定性

Abstract: Based on the Chongqing Fengjie Yangtze River Bridge with span of 460m,the influences of Geometry linear and nonlinear on the stability of long-span cable-stayed bridge was analysed in the construction stage and the service stage.The stability of the bridge was evaluated with calculating results from software ANSYS.

Key words: cable-stayed bridge, finite element method, the geometric nonlinear, stability analysis
