摘　　要：近年来,我国逐渐在一些桥梁结构中使用了可提高结构抗震性能的减隔震装置,如隔震支座、阻尼器(地震响应校正装置)等。对应用较广的粘滞阻尼器和Lock-up装置的工作机理进行了介绍,对其在连续梁桥抗震中的应用进行了研究,通过实际桥例探讨了两种装置对连续梁桥抗震性能改进的有效性,并对其实用的局限性也进行了分析。研究的结果可供桥梁工程设计人员和科研人员参考。Isolation bearings, damping systems （seismic modified response or energy dissipation systems） are being employed in China to provide enhanced protection for new or retrofit bridges. This paper introduces the working mechanism of viscous damper and lock - up devices, whose utility and applicability are demonstrated by comparison with conventional configurations for continuous girders. Examples of applications are presented. The results may be referenced by the researchers or bridge designers
