摘要

山坡展线桥因其高墩及各墩高差大对抗震不利,抗震概念设计应采取措施力求减小各墩的刚度差。以赛果高速高墩展线桥抗震概念设计及抗震性能分析为例,介绍了高墩展线桥抗震设计的基本过程,经采用变截面箱型墩和减隔震支座,使结构在偶遇地震作用下不出现破坏,在罕遇地震作用下结构经修复能继续使用,达到了抗震设计的目标。
In order to adapt the restriction of geography,the bridges in the mountainous areas have some high piers and the height difference between the piers is big which is disadvantageous in anti-seismic capability of the bridges.Some measures should be taken to reduce the stiffness difference between the piers in seismic conceptual design.Taking the seismic conceptual design and seismic performance analysis of the Sai-Guo highway route development bridge as an example,the seismic design processes of the bridge are introduced.By the use of variable cross-section box type pier and isolation bearing,the structures do not damage in frequent earthquake and under the rare earthquakes the structure can be used continuously after repairing.The results show that the structure design can reach the seismic performance objective.
