针对铁路既有线提速后圆柱形桥墩横向振幅超限问题,对桥墩进行检算,提出增设翼式钢筋砼板的加固设计方案,经现场振动测试验证,可有效提高桥墩横向刚度,改善桥墩横向振动状况。
Aiming at the over-limit of transverse amplitude of cylindrical pier after speeding up of existing railway lines, the bridge piers are checked, and the reinforcement plan of adding reinforced concrete slab is proposed. The on-site vibration test can effectively improve the lateral stiffness of pier and improve the lateral vibration of pier situation.
