摘要
为研究独柱墩桥梁在地震作用下的物理力学性质及抗震性能,室内设计并制作了标准比例圆形截面独柱墩简支梁桥模型。通过输入E1 Centro地震波,开展了柱墩桥梁的振动台试验,并提出合理的加固措施建议。研究认为,在独柱墩桥梁的设计与加固中,应当对独柱固定墩的结构与强度进行强化。
To study the physical and mechanical properties and aseismic performance of the single-column pier bridge under the action of earthquake, an indoor model of single-column pier simple supported beam bridge with circular section in standard scale is designed and fabricated. By inputting E1 Centro seismic wave, the shaking table test of column pier bridge is carried out, and the reasonable reinforcement measures are proposed. The study suggests that the structure and strength of single-column fixed pier should be strengthened in the design and reinforcement of the singlecolumn pier bridge.
