摘要
根据空间有限元计算模型，采用混合结构形式，以福建省沙县单塔悬索桥为研究对象，运用时程分析法，分析在地震波作用下主要结构参数对单塔悬索桥的动力特性及地震响应的影响，综合了单塔悬索桥的抗震性能，为推广和发展此类悬索结构提供了理论依据。
Based on the triaxial finite element method and the mixed structure form, the effects of single tower suspension bridges in Shaxian County are analyzed. The effects of structural parameters on the response of single tower suspension bridge to the fluctuating earthquake are presented according to step by step interaction. In the end, the dynamic characteristics and the anti seismic properties are put together, and it is the basis for the designs in popularizing and developing the kind of suspension bridge.
