摘　　要：为研究钢筋混凝土公路桥梁独柱式桥墩的抗震性能,对承受不同顶部集中荷载的三个桥墩模型进行了拟动力试验,试验输入的是EL-Centro南北方向的地震加速度记录。根据试验结果对试件的延性、恢复力特性、累积滞回耗能等性能进行了研究。In order to research the seismic resistance performance of single reinforced concrete bridge column pier, pseudodynamic test on 3 column pier models under different axial loading is conducted, and the seismic wave applied in the test is EL-Centro（1940NS） earthquake acceleration records. Based on the test results, column pier＇s ductility, resilience character and accumulated hysteresis dissipated energy are investigated.
