浅谈大跨度有黏结预应力梁后张法施工应用技术

Discussion on the Application Technology of Post Tensioning Method for Large Span Prestressed Beams with Bonded Tendons

预应力技术能够使结构的使用性能得到切实改善,当前已在国内外得到了广泛的应用,尤其是对大跨度、承受动力荷载的结构和不能够出现开裂的结构,其应用有着十分重要的作用。其中后张预应力技术,因其不需要台座,能够曲线配筋等优势的存在,在大体积混凝土机构得到了相对普遍的应用。

With the continuous development of technology, which can make the performance of structure has been improved effectively, at present at home and abroad has been widely used, especially for the large span or under dynamic load of the structure,and can not appear crack structure, plays a very important role in its application.The post tensioning technology, because it does not need to curve pedestal, reinforcement and other advantages, applications have been relatively common in large volume concrete mechanism.
