摘　　要：结合某在建高墩大跨曲线T形刚构桥的施工监控项目,建立其三维空间有限元模型,分析了施工中各种荷载对曲线T形刚构桥结构行为的影响,研究了最大悬臂和成桥状态的应力与变形,得出了施工过程的受力和变形规律。Combined with construction monitoring engineering of a building high pier large span T-typed steel frame bridge,the three dimensional space finite element model was built,various load influences on circular T-typed steel frame bridge was analyzed,the largest cantilever and dead load state stress and deformation was studied,the stress and deformation rules in construction process was obtained.
