| 摘 要： | 隔震技术作为当前最有效的结构减震控制技术之一，在世界各国高烈度地区广泛建造。随着隔震技术的大范围推广，建造工况更为复杂的隔震工程随之不断涌现。系统深入研究复杂地震激励下隔震结构地震响应，是隔震工程长期安全服役的重要保障，也是隔震技术能够不断完善和推广的坚实基础。本文从复杂地震激励涵盖的多维地震、近场和近断层地震、行波效应以及土与结构相互作用四个主要方面入手，依据国内外相关文献开展综述，探讨了复杂地震激励下隔震结构研究存在的问题，并对此进行展望。

| Abstract: | As one of the most effective structural shock absorption control technologies, seismic isolation technology is widely used in high-intensity regions in various countries. With the widespread promotion of isolation technology, isolation projects with more complicated construction conditions have emerged. The systematic study of isolated structures seismic response under complex earthquake excitation is an important guarantee for the long-term safe service of isolated projects and a solid foundation for the continuous improvement and promotion of isolation technology. First, this paper addresses the four main aspects of multi-dimensional earthquakes, including complex seismic excitation, near-field and near-fault earthquakes, traveling wave effects, and soil-structure interaction. Then, a review of relevant literature is presented to discuss existing problems in isolated structures under complex seismic excitation. |
