预应力混凝土梁桥具有结构自重小,跨度大的特点,所以,已经被广泛的运用于公路,铁路及城市立交等大型工程当中。预应力作为预应力混凝土梁桥的主要受力体系,关系到桥梁的使用安全及使用寿命。文章结合桥梁施工控制需要,探讨了大跨度连续梁桥施工控制的理论方法及监控工作流程,为连续梁施工控制提供一些经验,保证工程的顺利进行。
Prestressed concrete girder bridge has the characteristics of small structure, large span, so it has been widely used in highway, railway and city interchange and other large projects. As the main stress system of prestressed concrete girder bridge, prestressing relates to the safety and service life of the bridge. Combining with the need of bridge construction control, this paper discusses the theory and method of construction control of long-span continuous bridge, and provides some experiences for the continuous beam construction control to ensure the smooth progress of the project.
