摘要

以西宁通海路跨越湟水河斜拉桥为研究对象

建立全桥三维空间有限元模型

在半漂浮结构体系下

按照考虑桩-土-结构相互作用与不考虑桩-土-结构相互作用

分别计算了动力特性

分析了桩-土相互作用对结构动力特性所产生的影响。考察了结构的刚度和边界条件设置情况

在动力特性计算基础上

采用地震动力时程分析方法

考虑拉索垂度及支座的非线性影响

同时计入桩-土-结构相互作用

采用不同等级的地震波输入

分析结构地震动力时程响应

考察结构的抗震性能

并对结构抗震设计提出指导原则及设防建议

改进了构造措施

为同类较宽独塔单索面斜拉桥抗震分析提供了工程实践参考经验及有效的地震响应分析方法。

Abstract

Three-dimensional finite model for Tonghai road cable-stayed bridge on the Huangshui River in Xi′ning is established in this paper.The dynamic responses of the bridge with semi-floating systems is studied with or without the consideration of pile-soil interaction.The influence of pile-soil interaction on the dynamic responses of bridge structure is analyzed.The structural rigidity and boundary conditions of the bridge are also examined in this paper.On the basis of the above analysis result

the dynamic responses of bridge structure is studied by using seismic history analysis method.The influence of cable sag and bracket as well as the pile-soil interaction are also considered in this model.The seismic performance of structure is analyzed and some guiding principles are proposed for seismic design of the bridge.The study can provide valuable engineering experience and efficient method for seismic response analysis of cable-stayed bridge with single tower

single cable and wide bridge deck.
