摘　　要：采用悬臂施工方法的预应力混凝土连续梁的形成要经过一个复杂的过程,施工工序和施工阶段较多,各阶段相互影响,须对该类桥梁的施工过程进行控制,而不同的合龙顺序直接影响悬臂施工过程中的施工控制。The construction of pre-stressed concrete continuous girder by the cantilever construction method needs a complex process. There are more construction sequences and construction stages. The stages interact with each other. It is necessary to control the construction process of this bridge. And the different closure sequences will directly influence the construction control in the cantilever construction process.

关 键 词：连续梁 合龙顺序 施工控制
