摘　　要：随着桥梁预制拼装施工技术的推广,预制拼装桥梁立柱的连接构造和抗震性能等相关问题的研究受到广泛关注。以实际工程为背景,针对采用灌浆金属波纹管新型联接构造的预制拼装立柱进行抗震性能拟静力试验研究,制作2个缩尺比为1:3的试验试件模型,进行了整体现浇桥墩和灌浆金属波纹管连接预制拼装桥墩拟静力循环加载试验。对试验试件的损伤状态、位移延性、残余变形和等效黏滞阻尼比等性能指标进行描述,并与整体现浇混凝土桥墩进行比较和讨论。试验研究结果表明,采用灌浆金属波纹管联接的预制拼装立柱损伤主要集中在柱底接缝处及塑性铰区域处,该类预制立柱具有与传统现浇钢筋混凝土桥墩相近的抗震性能。As the development of bridge prefabricated assembly engineering,the connection construction and anti-seismic performance of prefabricated assembly pillars attracted a wide spread attention on research. In this paper,a anti-seismic performance pseudo static test of prefabricate assembly pillar connected with grouting metal corrugated pipe is proposed,and 2 test models with the scale of 1： 3 is produced and the pseudo static cyclic loading test is proposed. Comparing and discussing the performance index such as damage condition,ductility,residual deformation and equivalent viscous damping ratio,the results shows that the main damage of prefabricate assembly pillar connected with grouting metal corrugated pipe is concentrate upon the seam crossing of the pillar base and plastic hinge field,and the seismic performance of this prefabricated pillar is similar to the traditional cast-in situ reinforced concrete pillars.
