| 中文摘要: |
| 安徽五河淮河桥大桥为混合梁斜拉桥，跨径布置为(246+125)m，为独塔双索面塔墩梁固结体系。利用Midas/Civil建立空间杆系模型进行整体静力分析，确定塔墩梁部位四种最不利荷载工况，得到其活载影响线加载位置和荷载大小。再利用大型通用有限元软件ANSYS建立塔墩梁固结处三维实体模型进行受力分析，为设计与施工提供科学理论依据。 |
| 英文摘要: |
| The Huaihe and Five Rivers Bridge of Anhui is hybrid girder cable stayed bridge, with span arrangement (246 +125) m and single tower double cable planes tower pier beam consolidation system. Midas/Civil is used to establish a space truss model for the overall analysis to determine the most unfavorable parts of the tower pier beam loading conditions. With the large general purpose finite element software ANSYS, three dimensional solid model tower pier beam consolidation is established, which provides scientific and theoretical basis for the design and construction. |
