以某大跨高铁连续刚构桥为研究对象，利用有限元程序ANSYS建立了该桥桥墩0号块的空间有限元计算模型，分析了0号块成桥运营阶段横截面的应力分布规律。结果表明，该桥桥墩0号块各部位均满足规范要求，位于横隔板处的截面，其翼缘板端部应力集中和剪力滞后现象较严重。计算结果已为该桥设计提供了依据，对同类桥梁0号块设计具有参考价值。

Taking a long bridge as an example in the paper, the finite element analysis program ANSYS is applied to estab- lish a three-dimensional solid finite element computational model of segment No. 0, the laws of stress distribution in the cross sections of the box girders are analyzed under operation stage. The results show that the stress of segment No. 0 are in good agreement with the current codes except the manhole part of the diaphragm. The results have been used for the design of the bridge and can be of great benefit for the similar projects.
