摘　　要：本文以(85+130+85)m连续梁桥为工程背景,考虑铅芯橡胶支座的非线性特性和桥梁结构的相互影响,在建立连续梁桥全桥有限元动力分析模型的基础上,应用非线性时程反应分析方法,对连续梁桥在铅芯橡胶支座的减震性能进行分析研究,可为连续梁桥的减震设计提供了重要参考。Considering the interaction between nonlinear characteristic of lead rubber bearing and the bride structure, and based on the establishment of the model of dynamic analysis of finite element on （85＋130＋85） m concrete continuous beam bridge, the dynamic input are response of seismic absorption and its impact under the excitation calculated by time-historical analysis. Some valuable results are obtained, which can provide the meaningful reference for the design of seismic absorption on the （85＋130＋85） m concrete continuous beam bridge.
