公路桥梁施工中预应力施工技术的应用研究

Study of the Application of Prestressed Construction Technology in the Construction of Highway and Bridge

预应力施工技术在桥梁中的使用越来越广泛。在桥梁公路正式使用之前对道路桥梁进行预应力施工，会使道路桥梁的结构更加紧实。在使用过程中减少弹性形变，并减少桥梁变形和开裂，使得桥梁的使用寿命得到了很大提升。

The prestressed construction technology is used more and more widely in the construction of bridges. Prestres-sed construction before the of icial y use of highways and br-idges can make the structure more compact. It can educe the elastic deformation in the process of using bridges, and reduce the deformation and crack of bridge, so as to extend the service life of the bridges.
