摘　　要：考虑铅芯橡胶支座和桥梁结构的非线性特性 ,把支座和桥梁当作一个整体考虑 ,建立连续梁桥隔震体系全桥模型。通过大量的时程分析 。In this paper, the dynamic characteristic of continuous bridges equipped with isolation bearings are investigated by nonlinear time-history analysis. The property of seismic excitation and the structural parameters of bridge are changed. The nonlinear properties and mutual effect of lead-rubber bearing and bridge structure are also considered.

关 键 词：铅芯橡胶支座 地震响应 连续梁桥 隔震体系 动力特性
