| 摘 要： | 预应力混凝土构件中通常布置有多束预应力束，在施工设计中需要考虑预应力束的张拉顺序，合理的进行预应力筋的张拉。采用有限元程序ANSYS对不同的预应力束张拉顺序下某大桥主粱被动锚固区的局部应力进行分析计算，计算结果对同类桥梁的设计施工有一定的参考价值。

| Abstract: | Prestressed concrete structures in the layout have usually prestressed beam beam,the construction needs to be considered in the design of prestressed beams tensioned order,and to take a reasonable tension.In this paper,using the finite element program ANSYS to analyze the partial stress of passive anchorage zone of a bridge under the different tensioned order of prestressed beams,the calculation results has some reference value for the same design and construction of the bridge. |

| Keywords: | prestressed beams tensioned order passive anchorage zone partial stress analysis |
