摘　　要：从近断层地震动特征、近断层区桥梁结构动力响应特点、影响参数、抗震设计理论及规范等几个方面,分析了当前近断层地震作用下桥梁结构抗震设计的研究现状和最新进展,总结了研究中已取得的成果和结论,指出了研究工作中的不足,并对今后的研究工作进行了展望.In this paper, the state and research progress of seismic design for bridge structure subjected to near-fault earthquake are analyzed. The results and conclusion of research are summarized according to the characteristics of near-fault earthquake ground motions, characteristics of dynamic response for bridge structure near active fault and its sensitive parameters of near- fault earthquake ground motions, and research development of seismic design seismic design theory and code. Some existing problems at present are mentioned, and also the direction of the future research is put forward.
