摘要
文章主要阐述了后张法预应力在桥梁施工中孔道设置、穿束、张拉、压浆等关键工序的施工和质量控制,并介绍了千斤顶活塞伸长值的理论计算方法。
The article mainly presents the construction and quality control of the key construction process e.g. pore lay-out, steel bar through, tensioning and jacking in post-tensioned prestressing of bridge construction. It also introduces the theoretical calculation method for the elongation value of the jack ram.
