摘要
金婺斜拉桥拉索设计拉力高达10700kN,为国内罕见。运用有限元理论和SAP91、ADNIA电算程序分析了该桥索梁锚固处的应力以及索力对主梁梁段内力的影响。根据应力分析结果,确定了构造及预应力筋设计,并进行了现场应力测试。实践表明,该桥索梁锚固分析方法是可行的,索梁结构方式是安全的。
The cable tension force of the Jinwu Cablestayed Bridge as high as 10 700 kN is rarely seen in our country.In this paper,the finite element method and both SAP91 and ADINA programs are used to analyse the stress conditions of joints connecting cable and the girder.According to the stress conditions,some design measures are also demonstrated.
