摘　　要：多次震害经验表明,通过在上部结构和地基之间设置减隔震支座,利用橡胶垫的变形使上部结构的振动周期延长,利用钢构件的屈服或者滑动摩擦耗能来达到消能减震的目的,是一项有效的防震减灾措施。论文从减震机理、性质及应用等方面系统阐述和总结了拉索减震支座、叠层橡胶支座、球形抗震支座以及若干新型减震支座的研究成果,对未来新型减隔震支座的研究方向进行了展望。The experiences of several destructive earthquakes suggest that it is an effective seismic mitigation measure by setting up seismic isolation bearings between the structure and the foundation,using the deformation of rubber mats to make the period of structure longer,and using the yielding or sliding frictional energy dissipation of steel members to achieve the purpose of energy dissipation and earthquake mitigation.This paper systematically describes and summarizes the research results of cable-sliding friction aseismic bearing,laminated rubber bearings,spherical seismic bearings,and several new types of damping bearings from the aspects of seismic damping mechanism,properties,and applications,and finally provides an outlook on the future research direction of newtypes of vibration isolation bearings.
