摘要
采用有线位移理论对不设置隔震系统和设置隔震系统的连续刚构桥进行地震振动特性分析，并对隔震性能作出简单评价。本文以某公路大桥为工程背景，探讨隔震技术在连续刚构桥中的应用。
The paper analyzes the earthquake vibration characteristics and briefly evaluates vibra-tion isolation performance by finite displacement theory in the continuous rigid frame bridge withvibration isolation system and without vibration isolation system. The paper approaches the appli-cation of the vibration isolation technology in the continuous rigid frame bridge taking a certainhighway bridge as the project background.
