| 摘 要： | 在对大跨径斜拉桥整体结构有限元分析的基础上,应用子模型法对斜拉桥塔梁墩固结位置进行了有限元结构受力分析,计算了4种不同工况下结构的应力应变状态。研究表明:子模型法可以更为精确有效地计算斜拉桥塔梁墩固结处的应力分布情况,计算结果可作为大跨径斜拉桥塔梁墩固结处局部设计和施工的参考依据。

| Abstract: | Based on the finite element analysis of the whole structure of the long-span cable-stayed bridge,the sub-model method was applied to do finite element structural stress analysis of the pylon-girder-pier joint,and the stress and strain of the structure were calculated in four different working conditions.The research shows that sub-model method can calculate the stress distribution of the pylon-girder-pier joint more accurately and the calculating results can be considered as the reference to the design and construction of fixed tower-pier-beam part of the long-span cable-stayed bridge. |
