| 摘 要： | 本文介绍了北京市东便门立交11号、12号桥的模型实验、现实实测和有限元计算对比分析成果,并针对端部支座反力分布、截面剪应力分布、跨中、中墩截面应力分布、全桥挠度等进行了分析。对单柱式连续弯箱梁桥内力变化进行了初步探讨,为此种桥型的推广使用提供了有益的参考数据。

| Abstract: | This paper provides information on the model test, on-site measuring and the result of comparison analysis by finite element on Beijing Dongbianmen No.11 and No. 12 interchanges.Jacking force at the end distribution, cross section shearing stresses distribution, the section normal stress distribution on mid span and on intermediate pier, and the brdge deflection are analysed also. Furthormore, the preliminary discussion, which is about the internal forces changes on single pier supported curved continuous box beam bridge, provides effective reference data for speading and applying the interchanges like this shape. |
