| 摘 要： | 该文通过有机玻璃模型试验和MIDAS仿真分析,对京津公路立交桥D匝道桥进行了三种预应力张拉顺序的对比研究,详细分析了预应力对曲线箱梁桥力学性能的影响,结果表明不同的张拉顺序对预应力混凝土曲线梁桥的力学性能影响较大,并给出了较为合理的张拉顺序。 |
| 关 键 词： | 曲线梁桥 预应力 张拉顺序 |

| Abstract: | Through the plexiglass model test and MIDAS artificial analysis, the article contrasts and studies three pre-stressing tension sequences for Ramp D of Jingjin Expressway Interchange, and analyzes in detail the pre-stressing influence on the mechanics performance of curved box girder bridge. The result makes clear that the different tension sequence will greatly influence the mechanics performance of the pre-stressed concrete curved girder bridge, and gives the more reasonable tension sequence. |
| Keywords: | curved bridge pre- stressing tension sequence |
