| 摘 要： | 曲线梁桥由于其结构自身存在着弯扭耦合问题，因此其设计、施工及研究的难度比直线桥大得多。文章以某弯曲宽箱梁为依托工程，运用有限元软件AN-SYS建立简支曲线钢箱梁模型，对其空间受力性能进行分析，得出了其在自重作用下的应力状态和支座处剪力滞效应规律。

| 关 键 词： | 弯曲宽箱梁 受力性能 剪力滞效应 应力分布 |

| Abstract: | Due to its own torsion coupling problem existing in the structure of curved girder bridge,its design, construction and research are much more difficult than straight bridge. Relying on the engineering of a curved wide box girder, this article established the simply curved steel box girder model by using the finite element software ANSYS, analyzed its spatial force performance,and obtained its stress state and its rules of shear lag effect at the bearing seat under the impact of self weight. |

| Keywords: | Curved wide box girder Load-bearing performance Shear lag effect Stress distribution |
