摘要
结合申张线金港段江海大桥工程实例,采用有限元法建立三肋钢管混凝土系杆拱桥模型。通过计算模型进行结构屈曲分析,得出失稳模态以及稳定安全系数,再计算出拱桥部分构造参数对结构体系稳定的影响。
According to the engineering example of Shenzhang Line Jingang section of Jianghai Bridge, the three arch ribs CFST tied arch bridge model by finite element method is established to make structure buckling analysis. Then, the instability modes and relative buckling safety factors are obtained, and moreover, the formation parameter influence of the arch bridge on the structure system stability is calculated.
