| 摘 要： | 临时支墩是连续梁现浇施工过程中的辅助支承结构，其稳定性将直接影响到施工质量及安全性。文章结合工程实例对连续梁悬臂施工临时支墩进行了设计，以现有稳定计算理论为指导，建立了稳定分析的有限元模型，给出了结构在特定荷载工况下的稳定系数及失稳模态，弹性稳定满足要求，为以后同类桥型的施工提供参考。

| Abstract: | Temporary buttress is temporary supporting structure in the construction process of cast-in-place continuous girder.The stability of the temporary buttress directly affects the quality and safety of construction.Based on certain engineering example,the temporary buttress of continuous girder cantilever construction is designed.Under the guide of the existing stability theory,the finite element model for stability analysis has been built.Its stability factor and the instability mode are given under the speci... |
