摘　　要：分析了独柱墩弯桥的受力特点,针对独柱墩弯桥桥中轴线外侧重力大于内侧重力,容易发生倾覆的现象,提出一种墩梁协作受力的加固技术,采用钢绞线将主梁与墩柱联系在一起,在发生倾覆时提供抵抗力矩防止桥梁倾覆。通过Midas/Civil软件进行定性的数值分析发现,所提出的加固技术能够有效地减小支座负反力,达到减小倾覆发生可能性的目的。In this paper, the stress characteristics of single - column piers are analyzed. Aiming at the phenomenon that the lateral gravity of the middle axle of the single - column pendulum bridge is greater than the inside gravity, it is easy to overturn. A reinforcement technique is proposed, the line connects the main girder to the pier and provides the resistance torque in the event of overturning to prevent the Through the numerical analysis of Midas/Civil software, it is found that the proposed can effectively reduce the negative reaction force of the bearing and achieve the purpose ty of overturning. bridge from overturning. reinforcement technology of reducing the possibility of overturning.
