| 摘 要： | 预应力张拉是预应力混凝土构件施工的重要环节。为考察预应力张拉次序对混凝土体的影响，本文利用大型有限元软件ANSYS对30m装配式后张法预应力混凝土空心板梁的张拉试验进行了有限元仿真，并探讨了在各种不同的张拉次序下空心板粱应力及变形的变化规律。根据仿真计算结果给出了合理的预应力筋张拉次序。

| Abstract: | The prestressed tension is an important part of the prestressed concrete component construction.In order to find out the influence on the concrete hollow slab of different tension sequence,in this paper,the 30 m assembled post tensioning concrete hollow slab is simulated by the means of finite element analysis software ANSYS. The variation of the hollow slab's stress and strain are discussed according to the result of the different tensioning sequence, then, the reasonable sequence of tensioning prestressed steel wires is put forward. |
