摘　　要：桥梁双柱墩在国内外中小跨径公路桥梁和城市高架桥中应用非常广泛,但在历次破坏性地震中震害普遍严重。为了揭示桥梁双柱墩在地震作用下的破坏机理,发展具有可恢复功能的防震桥梁双柱墩,实现从双柱墩结构到桥梁工程、再到交通线路乃至整个交通网络的全寿命周期抗震性能设计,对桥梁双柱墩抗震问题的研究进展进行评述。首先总结汶川大地震和国外重大地震中钢筋混凝土桥梁双柱墩的震害情况并分析其特征,主要破坏形式有墩柱的弯曲破坏、弯剪破坏、剪切破坏,间系梁的纵向开裂及其与墩柱节点的断裂,盖梁梁体的斜裂缝、冲切开裂及其垫石和挡块的剪裂、剪断、撞碎等。再从抗震性能试验、非线性力学行为及数值模拟、间系梁减震耗能、损伤控制与可恢复功能结构体系、ABC双柱墩及其在强震区的应用问题、抗震加固方法和抗震设计理论等方面对桥梁双柱墩相关的抗震问题研究进展进行系统梳理与评述,进而指出桥梁双柱墩应用与研究中存在的问题。在此基础上,结合当前地震工程领域的主要发展趋势和前沿热点问题,如子结构混合模拟试验、可恢复功能结构和交通系统、多次多灾种耦合作用、全寿命设计、大数据和人工智能等,对双柱墩结构及其桥梁体系未来的研究方向进行展望。Bridge double-column bents are widely used in highway bridges of small or medium spans and urban viaducts around the world.However,bents have suffered serious damage in previous devastating earthquakes.To reveal the damage mechanism of bridge double-column bents during earthquakes,to develop bridge double-column bents with earthquake resistance,and to realize the life-cycle seismic performance design from double-column bents for bridge engineering,traffic lines,and the entire traffic network,research progress on the seismic performance of bridge double-column bents is reviewed.Reports of the damage to reinforcedconcrete double-column bents during the Wenchuan earthquake and major earthquakes worldwide are summarized,and the damage characteristics are analyzed first.The main damage types include flexural failure,shear failure,and flexural-shear failure of columns,longitudinal cracking of tie beams and their joints with columns,and oblique cracking of cap beams caused by the punching,shearing,and crushing of cushion stones and shear keys.Subsequently,the research progress on the seismic performance of bridge double-column bents is reviewed with respect to seismic performance tests and numerical simulations of the bents,seismic performance of tie beams,damage control and resilience structure systems,accelerated bridge construction and its application problems in strong earthquake areas,seismic retrofit methods,and seismic design theories.Then,problems in the research on and applications of bridge double-column bents are discussed.Finally,the directions of future development for double-column bents and bridge systems are forecast based on the main development trends in the field of earthquake engineering,such as hybrid simulation testing,earthquake resilient structures and their transportation systems,multiple disasters and their coupling effect,life-cycle design,big data,and artificial intelligence.
