摘　　要：分析独柱墩连续曲线箱梁倾覆失稳破坏过程,综合考虑其临界倾覆时的实际空间受力状况,运用计算机辅助图形设计和有限元计算分析技术,结合工程实例,提出一种计算思路清晰、方便快捷的连续曲线箱梁抗倾覆稳定性计算方法,为连续曲线箱梁的设计、检测计算分析提供借鉴参考。The process of overturning and damage of single-column pier continuous curved beam bridge has been analyzed. Taking into account the real stress state of the girder when overturning, the computer graphics aided design and the analysis technology of finite element method have been adopted, being combined with practical engineering, a clear and quick method for the calculation on the overturning of single-column pier continuous curved beam bridge has been put forward, wich could provide valuable suggestion for the design of single-column pier continuous curved beam bridge.
