摘要
在总结连续刚构桥抗震设计研究现状的基础上,运用地震反应分析的基本理论,以某刚构桥为工程背景,对连续刚构桥进行了空间地震反应谱分析和地震反应时程分析。主要研究了桩-土相互作用对桥梁地震反应的影响;同时对反应谱分析与时程响应分析的计算结果进行分析;本文对连续刚构桥的地震反应分析得到的有关结论,可为连续刚构桥梁的抗震设计提供参考。
In this paper,two methods including spectrum response analysis and time-history analysis of earthquake are applied to Xin Zhou bridge based on the basic theory of the earthquake response analysis. The main work in this paper includes that considering the influence of the pile-soil interacion to the seismic response of the bridge;Obtaining some valueable conclusions based of the study on results of response-spectrum and tilne-history. in this paper,from the earthquake response analysis of the continuous rigid-fralne bridge, these obtained conclusions will give some refences for practical earthquake resisting designing of continuous rigid fralne bridges.
