摘　　要： 首先介绍了一种新型三维隔震(振)支座,该支座由联接件、竖向隔振支座和水平隔震支座组成。竖向隔振支座和水平隔震支座具有较小刚度,采用该类型支座的隔震结构,其竖向基频和水平基频可远离地铁、铁路振动和地震的主频,从而实现竖向隔振和水平隔震作用。其次介绍了该三维隔震(振)支座在某一地铁平台上部结构中的应用情况,对该类型支座进行了竖向性能和水平性能试验。最后对三维隔震(振)结构与传统结构进行了地铁运行时结构振动的对比测试。测试结果表明:三维隔震(振)系统对振动的高频信号具有显著衰减效果。 An innovative 3D isolator is introduced first, which is composed of connecting plate, vertical rubber pad and the horizontal rubber bearing. The vertical rubber pad and the horizontal rubber bearing have very low stiffness, and in the isolated building both vertical and horizontal natural frequencies can be designed far from metro, train and earthquake main frequencies to insulate both environment vibration and earthquake. In addition, the application of the 3D devices to a building above a platform of subway is introduced next. Both the vertical and horizontal properties of the devices were being tested. Finally, the in situ tests of isolated building and non-isolated building were carried out. The comparing test results show that the 3D isolation system is effective to reduce the building responses in high frequency domain.
