| 摘 要： | 由于预应力混凝土曲线梁桥结构本身的特点，在荷载作用下弯矩与转矩的相互耦合作用，其支承形式应根据曲率半径的大小、上下部结构的总体布置决定，从而选用对结构受力有利的支承形式，并由此决定全桥的力学计算模型。文中针对不同的支承形式对曲线梁桥转矩分布的影响进行了初步的研究，通过对工程实例的计算分析得出了一些有益的结论。 |
| 关 键 词： | 曲线梁桥 支承形式 转矩分布 |

| Abstract: | Because of the structural characteristics of prestress concrete curved beam bridges, bending moments and twist moments are coupled under loads. The bearing forms should be decided considering the curved radius, integrated the layout of the superstructure and the substructure. The advantageous structural bearing forms and reasonable calculation model may be chosen based on these. A preliminary research on the distribution of the twist moments caused by different bearing forms in curved beam bridges is given to demonstrate some useful conclusions in this paper. |
| Keywords: | curved beam bridges bearing forms distribution of twist moments |
