摘要
研究了斜拉板桥的动力特性。首先，以某斜拉板桥方案为例，建立了全桥空间动力分析模型。在此基础上，探讨了桥墩横向刚度对结构横向自振特性的影响，所得结果可供设计参考。
In this paper,the dynamic characteristics of slop tension slab bridges is investigated with a slop tension slab bridge project as an example,and a space analysis model of the completed bridge is established. Based on the mathematical model,the lateral stiffness of piers effects on the lateral free vibration of the structure is discussed,The result chained can be used for reference in designing.
