摘要
根据桥址处的地质条件、通航要求和净高限制等要求,桥型采用采用(81+81+229.5+81+81)m连续钢桁梁结构,利用软件建立有限元模型进行计算分析,重点计算了该桥的强度,刚度,稳定性和疲劳,结果表明该桥满足设计要求。
According to the geological conditions, navigation requirements and net height restrictions of the bridge site, the bridge type adopts(81+81+229.5+81+81)m continuous steel truss girder structure,USES the software to establish the finite element model for calculation and analysis, and focuses on the calculation of the strength, stiffness, stability and fatigue of the bridge, the results show that the bridge meets the design requirements.
