摘    要:依托预应力顶、底板钢束同时存在的连续刚构桥—老窝河特大桥,选取典型工况,应用有限元软件Midas/civil分析了预应力分批、同步张拉次序的不同对预应力损失的影响。研究表明先张拉顶板束预应力损失略小于先张拉腹板束。在实际工程中可根据现场条件选择合适的预应力张拉方式。

关 键 词:连续刚构桥  预应力张拉次序  预应力损失  Midas/civil

Abstract:This paper relies on the continuous rigid frame bridge naming Laowo Bridge whose roof beams and plate beams are concurrence. The sequence of prestress drawing effect including batch and synchronization on prestress loss were analyzed by using Midas/civil finite element software through selecting typical conditions. The results show that the loss of drawing roof beams first is small than drawing plate beams. In the actual engineering, we can choose the right sequence of prestress drawing according to the scene.
Keywords:continuous rigid frame bridge  the sequence of prestress drawing  the loss of prestress  Midas/civil
