摘要
通过动态测试 ,对独柱式连续梁弯桥的径向、竖向振动特性进行了分析。针对梁底抗震钢桩的被剪断现象 ,实测了大型重车通过时墩、梁的径向、纵向相对位移 ,得到了墩、梁平面相对位移的变化规律。同时对这种独柱式弯连续梁桥的抗震。
In this paper, through a dynamic test, the vibration characteristics of a continuous concrete curved beam bridge with isolated columns along radial and vertical direction are studied. Aimed at the phenomenon of shear fracture of earthquake resistant steel piers at the bottom of beam, the relative displacement between the beam and the bridge pier is measured when heavy loading wagons get across the beam. So the variable rule of the relative plane displacement is obtained. At the same time, a preliminary discussion about aseismatic and torsional property of continuous concrete curved beam with isolated columns is carried out.
