摘要
以湘潭市湘江四大桥主桥为研究对象,利用大型通用有限元程序建立斜拉拱桥的三维空间有限元模型,计算该桥梁结构的稳定安全系数,对桥梁的失稳特征进行分析。计算结果可为该桥的施工以及使用阶段的健康检测和维护提供参考。
Taking the main bridge of the 4th Xiangtan Xiangjiang River Bridge as the research obiect, this paper establishes a three-dimensional spatial finite element model for cable-stayed arch bridge, using the universal finite element program, calculates the stability safety coefficients of the structure of the bridge and also analyzes the instability characteristics thereof. The results of calculation in the paper may provide reference for the construction, health inspection and maintenance of the bridge at operation stage.
