摘　　要：为了揭示装配式桥墩连接形式的抗震性能,系统回顾和分析了相关研究进展.根据力学行为将装配式桥墩体系区分为等同现浇体系和非等同现浇体系,对相应的连接形式、性能、施工特点、工程实例进行了介绍,总结了常用的抗震性能提升手段和研究方法.结果表明:等同现浇体系与现浇体系接近,耗能能力强,应用广泛,非等同现浇体系具有自复位功能,但实现较为复杂;应用高强材料、新装置和混合体系能够有效避免接缝处过早破坏,提高抗震性能;理论分析、模型试验和数值模拟均能有效反映装配式桥墩的力学行为.最后,提出了推广装配式桥墩应用所面临的新挑战,阐述了体系层面分析、全寿命周期设计、韧性抗震3个方面的发展前景,为新的研究方向提供参考.To reveal the seismic performance of prefabricated piers with different connection forms,relevant research development was systematically reviewed and analyzed.According to the mechanical behaviors,the prefabricated pier systems were divided into emulative and non-emulative systems.The corresponding connection forms,performance,construction characteristics,and engineering examples were introduced.The common manners and research methods for improving seismic performance were summarized.The results show that the emulative system is similar to the cast-in-place system,possessing a strong energy dissipation capacity and being widely used.The non-emulative system features a self-recentering function but the realization is more complicated.The employments of high-performance materials,new devices and hybrid systems can effectively avoid the premature failures of connection joints,thus improving the seismic performance.Theoretical analysis,model test and numerical simulation can effectively reflect the mechanical behaviors of prefabricated piers.Finally,the new challenges in the application of prefabricated piers were put forward.The development prospects of system level analysis,life cycle design,seismic resilience were described,providing references for new research directions.
