| 摘 要： | 以江津粉房湾大桥为依托工程,对钢桁斜拉桥所存在的板桁温差效应进行分析,在参考各国规范对温差效应规定的基础上,提出了钢桁斜拉桥板桁温差效应分析方法。通过比较不同温差作用下钢桁梁与桥面板连接部位的变形和受力情况,研究温差效应对结构的影响程度,并提出了有效解决温差效应的措施。

| Abstract: | Based on the engineering of Jiangjin Fenfangwan Bridge,the thermal difference effect between orthotropic slab and steel truss of steel truss cable-stayed bridge was researched.By reference of thermal difference effect standards in many countries,the analysis method of thermal difference effect was proposed.By comparing stress and deformation of combining site of orthotropic slab and the steel truss at different temperatures,the influence of thermal difference effect on structure was studied and the solutions were put forward. |
