Earthquakes have a significant impact on the safety of long-span bridges,and seismic isolation technology is an important measure for bridge seismic resistance.This paper provided a detailed introduction to the existing repre-sentative seismic isolation devices for large-span bridges,analyzed the advantages,disadvantages,and applicability of each device,and summarized their seismic reduction effect calculation and analysis methods.Finally,the future develop-ment trends of bridge seismic isolation devices were discussed to promote the application of new seismic isolation tech-nologies in the field of bridge engineering.
