摘　　要：对隔震建筑采用1200型大直径叠层铅芯橡胶隔震支座进行了力学性能研究,并对其实施了系统性能试验.研究其竖向压缩性能、水平剪切性能、阻尼比和水平极限变形性能,指出竖向压力及水平剪切变形对大直径1200型隔震支座的性能影响.同时使其与Φ1100mm、Φ1000mm及Φ600mm型叠层铅芯橡胶隔震支座进行了对比分析.研究结果表明,中国生产的大直径1 200 mm型叠层铅芯橡胶隔震支座力学性能稳定可靠,可在实际工程中推广应用,并为高层建筑结构的隔震减震控制提供设计依据.Tests are conducted on mechanical characteristics of laminated lead steel-plate-laminated-rubber-bearing isolation bearing （D=1 200 mm） with an experimental study, including vertical compression property, horizontal shear property and ultimate deformation property. The influence of vertical pressure and horizontal shear deformation are obtained, analyzed and compared with three kinds of used type steel-plate-laminated-bearing isolation bearings （D= 1 100 mm; D= 1 000 mm; D=600 mm）. It is proved that the bearing （D=1 200 mm） made by China has good properties and can be extended use for in actual projects, providing designs foundation for the seismic isolation and shock absorption control of structural high-rise buildings.
