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。
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.
