利用大型通用有限元程序建立了中承式钢管混凝土拱桥的三维空间有限元模型,计算了桥梁结构的稳定安全系数,对桥梁的失稳特征进行了分析,计算结果可为该桥的施工以及运营阶段的健康检测和维护提供参考。
The three-dimensional finite element model of CFST arch bridge was established by using the large-scale general finite element program. The stability safety factor of the bridge structure was calculated and the instability characteristics of the bridge were analyzed. The calculation results could be used for the construction and operation of the bridge Stage of health testing and maintenance for reference.
