中文摘要：

为推动国内桥梁减隔震技术发展和促进相关规范完善,对中国、日本、美国等减隔震设计规范的发展历程、抗震设防目标、抗震设计和分析方法、构造措施及细节等进行对比分析,介绍了减隔震装置（支座）的性能要求和特性试验和原型试验技术要点。认为宜进一步在设计规范中细化设计方法、分析方法及构造措施要求等,重视减隔震装置性能检测及原型试验,增强抗震设计规范和技术标准之间的协调性。

英文摘要：

To promote the development of seismic isolation technology and design code for seismic isolation of bridges, a comparative study, which includes developing history, seismic design goal, seismic design and analysis methods, and design detailing of the codes for seismic isolation in China, Japan, and USA, is made. The technical points of performance requirement, system characterization tests, and prototype tests for seismic isolation are introduced. Furthermore, the clauses of design and analysis methods, construction detailing, system characterization and prototype tests in Chinese code for seismic isolation of bridges should be refined, and the coordination between seismic design code and technical norms of seismic isolation should be improved.
