| 中文摘要: |
| 斜拉-悬索协作体系桥作为一种新的超大跨径桥型，综合了悬索桥和斜拉桥的特点，国内外对这种桥型的研究尚少。本文根据空间有限元计算模型，对伶仃东航道斜拉-悬索协作体系桥设计方案进行了模态分析，分析了斜拉-悬吊协作体系桥的固有特性，讨论了不同主梁纵向约束方式和辅助墩的设置情况的影响，为此类桥型结构的动力性能分析提供了有价值的参考。 |
| 英文摘要: |
| As a new super\|long\|span cable\|supported bridge type, the cable\|stayed\|suspension bridges synthesize the characteristics of cable\|stayed bridges and suspension bridges. On the base of spatial finite element modal, the modal analyses results of the Lindin East Sea\|route cable\|stayed suspension bridge design project is obtained. The inherent vibration characteristics of cable\|stayed\|suspension cooperation system and the influence of longitudinal restraint conditions in main girder and assistant pier setting. The results can provide theoretic reference for the dynamic analyses of the cable\|stayed\|suspension cooperation system. |
