摘　　要：该文以欧拉弹性理论为基础,运用空间有限元法对高墩曲线连续刚构桥在施工最大悬臂状态下的T构进行稳定性分析。计算不同工况下的结构稳定特征值,以此对高墩曲线连续刚构桥的T构施工过程进行监控。Taking Euler Elastic Theory as the base, the article applies the space finite element process to carry out the stabilization analysis of T-frame of the high-pier curve continuous rigid frame bridge under the construction of the largest cantilever. The article calculates the character value of the structural stabilization under the different constructing conditions so as to monitor the construction course of T-frame of the high-pier curve continuous rigid frame bridge.
