介绍了粘滞阻尼器的力学性能和减振原理，并以一座自锚式悬索桥的抗振设计为实例，阐述了阻尼器参数及布置位置的选择，从理论计算上对比了该桥安装粘滞阻尼器前和安装粘滞阻尼器后的地震响应，从结果分析比较中说明了该自锚式悬索桥在多个地震波时程下，粘滞阻尼器都能有效的消耗地震能量，大幅减小了桥梁结构地震下的内力和位移，起到了很好的减振效果。

T his paper mainly introduces the mechanical properties and damping absorption principle of viscous damper .Taking the seismic design of a self-anchored suspension bridge as an example ,the pa-per discusses damper parameters and selection of layout position .The theoretical calculation shows the contrast of seismic response of the bridge before and after the installation of viscous damper .The analyses of the results show that viscous damper can effectively consume seismic energy and greatly reduce internal force and displacement of bridge structures ,w hen the self-anchored suspension bridge is in multiple seismic time history .Therefore ,it plays a very good damping effect .This research re-sults will be beneficial to engineering project applications .
