摘要
以K162 + 65 2 .9预应力空心板桥为例 ,介绍了后张法预应力钢绞线的张拉伸长量计算方法与控制技术。阐述了张拉、复核使设计预应力准确施加的方法 。
Taking K162+625.9 prestress cored slab bridge as example, the calculation methods of post tensioned extension value of prestress steel strands are introduced in this paper. by tension and check design prestress is correctly acted. At the same time the matters paid much attention in construction and calculation are given.
