摘　　要：为了实现大跨度梁桥结构的施工过程控制,对这类结构的成桥状态进行分析评价,以湖南攸水大桥(65+120+65)m为例,建立有限元模型,进行施工过程控制理论计算分析,通过现场实施、偏差对比,得出此梁桥在施工过程中以及成桥状态下主梁线形平顺,大桥各截面受力合理,结构安全可靠,符合设计要求。In order to achieve the construction process control of large span bridge structures,analysis of this kind of structure of the bridge state assessment,this paper takes Hunan Youshui Bridge(65+120+65)m for example,the finite element model is set up,control the construction process of the theoretical calculation analysis,through the implementation,a deviation in contrast,it is concluded that the girder bridge during construction and bridge state,the main girder linear smoother,bridge each section stress is reasonable,the structure is safe and reliable,comply with the design requirements.
