摘　　要：结合广东科学中心施工实践,探讨巨型钢结构联合采用大直径双橡胶隔震支座和单橡胶隔震支座进行基础隔震的施工技术,解决巨型钢结构隔震支座预埋件施工、隔震层与格构式巨型钢柱柱脚连接施工、巨型钢结构施工、隔震层构造施工等方面的技术难点,获得了良好的施工效果。重点阐述隔震支座下预埋钢板定位及固定、锚栓和螺栓套筒施工定位、螺栓孔开设、隔震缝施工等技术措施,确保隔震层的安全可靠。Based on Guangdong Science Center engineering, the application of base isolation construction technology on huge steel structure is discussed which uses lager diameter rubber double-isolators and single-isolators. The key points of construction technology and measures including isolators embedded parts, joints of isolation layer and huge steel column foots, huge steel structure and isolation layer structural measures are presented and the effects are excellent. The authors introduce location and fixture of embedded plate under isolator, construction location of anchor bolt and belt sleeve, setting of bolt hole and isolation joint construction in detail which can assure the safety and reliability of isolation layer.
