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。

关 键 词:斜拉-悬索协作体系桥  动力分析  模态分析  有限元模型

Abstract: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.
Keywords:cable\|stayed\|suspension cooperation system  modal analysis  finite element modal
