随着铁路桥梁的建设发展，大跨度桥梁不可避免的通过地震高烈度区。以一座4跨连续梁桥为例，通过非线性时程的分析方法，探讨摩擦摆式支座（FPS）在地震作用下的减隔震特性。分析研究结果表明：在地震作用下，装有FPS隔震支座桥梁比非隔震支座桥梁具有较好的减震效果；为优化设计带来空间。

With the development of the construction of railway bridges, some long-spanned bridges have to be built in highly- seismic regions. With a four-span continuous beam bridge as a practical example, by means of the no alinear dynamic time history analysis,a study is made of the earthquake-isolating characteristics of the friction pendulum-type be~tring （FPS）. Results of the research and analyses show that isolated bridges with the friction pendulum-type bearings are better than bridges without the friction pendulum-type bearings in reducing the effects of an earthquake on the bridges in high-intensity seismic regions and the research also helps to optimize the structural design of bridges.
