预应力混凝土连续梁桥的施工方法众多,其中悬臂浇筑和悬臂拼装施工法应用最为广泛。这种方法的采用,必然给桥梁结构带来较为复杂的内力和位移变化。因此,为了保证桥梁的施工质量和施工安全,对连续梁桥悬臂施工技术进行必要的研究和实践尤为重要。 There are many construction methods for prestressed concrete continuous girder bridges, of which cantilever pouring and cantilever assembly are the most widely used construction methods. The adoption of this method will inevitably bring more complicated internal forces and displacement changes to the bridge structure. Therefore, in order to ensure the construction quality and construction safety of the bridge, it is particularly important to carry out the necessary research and practice on the cantilever construction technology of the continuous beam bridge.
