摘　　要：基础隔震技术是一种利用减、隔震装置将结构与基准面解耦来降低主体结构地震作用的控制技术,近几十年来在诸多重要工程中取得了成功应用.结合我国相关规范新引入极罕遇地震作用的研究背景,介绍了近年来国内外橡胶隔震支座和摩擦摆支座的理论与试验研究成果,重点探讨了复杂环境条件下隔震支座的性能演变规律与相应的性能提升方法,进而分析了被动自适应隔震系统与组合隔震系统的研究动态,并总结了研究存在的不足,为基础隔震体系性能评估与提升的进一步研究提供参考.By using seismic isolation devices to decouple structures and the ground,the base-isolation technology works as one of the most effective techniques for protecting structures from earthquake events,and has been successfully applied in many important engineering projects for the past decades.Recently,an excessive earthquake level beyond the highest one in the traditional Chinese seismic design code was introduced in the newly revised version,and it is of great urgency to examine and promote the performance of base-isolated structure systems,so that they can accommodate large seismic responses due to such strong earthquake events.In the present paper,the development of studies on performance evolution and promotion of base isolation systems was reviewed and analyzed comprehensively. The recent theoretical and experimental research progresses on rubber isolation bearings and friction pendulum bearings were introduced. Special attentions were put on the performance evolution and promotion of those bearings under complex environmental conditions. Furthermore, the research progresses of self-adaptive and combined isolation systems were summarized and analyzed, and some critical shortcomings of the current studies were pointed out, which can provide a guideline for further research on base-isolation systems in the aspects of their performance evaluation and promotion.
