摘要: 以重庆某小区一座小半径曲线箱梁桥为背景,介绍了曲线梁桥的一般求解方法,并用有限元软件ANSYS对 预应力效应进行了数值仿真分析。结果表明,对于跨宽比值较小的曲线箱梁桥,宜采用空间实体进行受力分析,当 设置有抗扭支座时,预应力引起的内、外侧支座竖向荷载差异效不应被忽略。

Abstract: As the background of a small radius curved box girder bridge in Chongqing, A general analysis method of curved bridge has been introduced and the prestress effect is studied by the method of numerical simulation based on the finite element software ANSYS in this paper. The result of numerical simulation analysis shows that the space analysis should be adopted when the ratio of width/span is small and the difference between the inner vertical resistant reaction and the outer reaction caused by the prestress should not be ignored for the curved box girder bridge with torsion resistant

Key words: curved beam, prestress, numerical simulation, displacement
