| 摘 要： | 采用常规抗震设计方法设计的高墩连续梁桥,无论是滑动支座还是固定支座下的桥墩,在地震作用下的墩底内力和墩顶位移均较大。针对高墩连续梁桥这一特点,本文以某大型跨江桥梁的引桥工程作为分析实例,将目前在建筑结构中研究比较成熟的多种减、隔震技术应用于高墩连续梁桥,对其减震效果进行了探讨。分析结果表明,各减、隔震设计方案均有各自的优势及局限性,需根据桥梁结构的具体要求来选择适当的抗震、减震设计方案。

| Abstract: | The internal force of the piers bottom of high-pier continuous girder bridge in earthquake action,which was designed by conventional earthquake-resistant method,and the displacement of the piers peak of it are very large,whether the piers with sliding bearings or fixed bearings.According to the behavior of high-pier continuous girder bridges,the multi-seismic isolation technologies which have been applied to architectural structures more widely are discussed how to apply to high-pier continuous girder bridge.And a large bridge spanning the Yangzhi-river was taken as an example.The results show that all seismic isolation methods have their own advantage and disadvantage,and these methods should be chosen according to different high-pier continuous girder bridges. |
