Transverse anti-overturning catastrophe reinforcing design method for single-column pier bridge
The invention discloses a transverse anti-overturning catastrophe reinforcing design method for a single-column pier bridge. The method comprises the following steps that an anti-overturning system is arranged between a single-column pier and a middle cross beam; the anti-overturning system comprises an externally-attached steel plate, an upper anchor box, an inhaul cable system, a lower anchor box and an annular steel plate, the externally-attached steel plate is fixedly connected with the middle cross beam, and the upper anchor box is fixedly arranged on the externally-attached steel plate; the annular steel plate is fixedly connected with the single-column pier, the lower anchor box is fixedly installed on the annular steel plate, the upper end of the inhaul cable system is connected with the upper anchor box, the lower end of the inhaul cable system is connected with the lower anchor box, and the inhaul cable system is in a tensioned state. The system is low in cost and easy to install, rapid reinforcement can be achieved without interrupting the traffic interface, the framework is flexible to disassemble, and components are easy to replace and maintain. A plurality of inhaul cables are arranged according to the anti-overturning bearing capacity requirement, the anti-overturning price of a linear bridge and a curved bridge is achieved by changing the number of the upper anchor boxes and the number of the lower anchor boxes, the anti-overturning bearing capacity of the bridge is greatly improved, and the application range of the bridge is greatly widened.
本发明公开了独柱墩桥梁横向抗倾覆灾变加固设计方法，包括如下过程：在独柱墩与中横梁之间设置抗倾覆系统；所述抗倾覆系统包括外贴钢板、上锚箱、拉索系统、下锚箱和环形钢板，外贴钢板与中横梁固结，上锚箱固定设置于外贴钢板上；环形钢板与独柱墩之间固定连接，下锚箱固定安装于环形钢板上，拉索系统的上端与上锚箱连接，拉索系统的下端与下锚箱连接，拉索系统呈张紧状态。本发明成本低廉，易于安装，不需要中断交通接口可实现快速加固，构架拆解灵活，构件易于更换和维修。根据抗倾覆承载力需求设置多根拉索，通过上锚箱和下锚箱数量的变化实现直线桥和曲线桥的抗倾覆价格，极大的提高了桥梁抗倾覆承载力和适用范围。
