桥梁工程施工中后张法预应力施工技术探讨

预应力后张法施工能够提升桥梁构件的抗裂性、刚度等性能,采用减轻结构自重,增大桥梁跨径的方法来降低桥梁的总体投入,对提高桥梁的使用功能和建设经济性起到重要的作用。文章对如何使用该方法进行桥梁工程的施工展开研究,通过分析该施工方法的原理及如何控制施工质量,满足桥梁工程建设的技术要求和质量要求。

The construction of prestressed post-tensioning method can improve the crack resistance and stiffness of bridge members,reduce the structural weight and increase the bridge span to reduce the overall investment of the bridge,so it plays an important role in improving the use function and construction economy of the bridge.This paper studies how to use this method to carry out the construction of bridge engineering and,through the analysis of the principle of the construction method and of how to control the construction quality,meets the technical requirements and quality requirements of bridge engineering construction.
