| 摘 要： | 现浇箱梁独柱墩弯桥具有整体性能好、抗扭刚度大以及视觉通透、外形美观等优点。但结构的受力特点又决定了其抗倾覆稳定性对结构的安全性能存在极大影响。通过对某独柱墩连续箱梁弯桥结构抗倾覆稳定性进行验算，分析其原因，为消除相应桥型的安全隐患提供了依据。

| Abstract: | Box girder with single column pier has a better overall performance and torsional stiffness. At the same time, it has a good sight and good looking. However, the mechanical characteristics decide that its overturning resistant stability has great influence on the security of the structure. The paper calculates the overturning resistant stability of a continuous box girder bridge with single column pier to analyze the reasons of capsizes. It has big benefit to eliminate the hidden dangers of this kind of bridges. |
