预应力钢绞线在箱梁施工中的应用

The application of pre-stress stranded steel wire in box beam construction

结合四平至长白一级公路桥预应力钢绞线混凝土箱梁施工 ,介绍了预应力钢绞线混凝土箱梁的施工准备 ,预应力施工计算基本原理及预应力张拉施工工艺等方面的经验 ,通过张拉检测结果 。

Combined with pre stress stranded steel wire concrete box beam construction of the first level road bridge from Shiping to Changbei, the paper introduces the construction preparation of pre stress stranded steel wire concrete box beam, the basic principle of calculating pre stress construction and pre stress tension construction crafts. The results of tension detection prove that pre stress stranded steel wire has some certain reference on similar engineering construction.
