Study on the dynamic behavior and the seismic design of the bridge abutment newly built or renovated employing reinforced earth method

本文通过对桥台进行1g振动台模型试验和动力分析，研究了钢带配筋的存在、钢带长度、输入加速度大小和桥台墙体刚度对桥台和回填体动力性能的影响。这些结果表明，这种桥台加固对抗震是有效的，并表明了降低桥台墙本身刚度的可能性。

In this study a series of 1g shaking table model tests and dynamic analyses on the bridge abutment were carried out to examine the influence of the existence of steel strip reinforcement, the strip length, the magnitude of input acceleration and the rigidity of the abutment wall on the dynamic behavior of the bridge abutment and backfill. These results lead to the conclusion that this abutment reinforcement is effective on earthquake resistant and indicate the possibility of the reduction of the rigidity of the abutment wall itself.
