Single-column-pier transverse-bridge-direction anti-overturning reinforcing and limiting device
The single-column pier transverse bridge direction anti-overturning reinforcing and limiting device comprises a cover beam, a plurality of support mechanisms and a plurality of damping limiting stopper modules, the cover beam is arranged at the upper end of a single-column pier, the support mechanisms are evenly distributed at the upper end of the cover beam and located at the bottom of a transverse bridge, and the damping limiting stopper modules are arranged at the two ends of the cover beam respectively. According to the single-column pier transverse-bridge-direction anti-overturning reinforcing and limiting device, the bent cap is additionally arranged at the upper end of the single-column pier, the number of supporting points in the transverse bridge direction is increased, and therefore the purpose of improving the overall anti-overturning stability of a single-column pier bridge is achieved. Under the excitation action of a strong earthquake, relative displacement is generated among the transverse bridge, the single-column pier and the steel box; when the displacement is small, the damping stopper module provides relatively low stiffness and strength. Under strong earthquake excitation, the displacement response is increased, the damping limiter module provides higher strength, and meanwhile, the damping limiter module provides higher rigidity. The rigidity provided by the damping limiter module can limit the relative displacement between the transverse bridge and the single-column pier.
本发明公开了一种独柱墩横桥向抗倾覆加固限位装置，包括盖梁、多个支座机构以及多个阻尼限位器模块，盖梁设置在独柱桥墩的上端，多个支座机构均布在盖梁的上端并位于横桥的底部，多个阻尼限位器模块分别设置在盖梁的两端。该独柱墩横桥向抗倾覆加固限位装置通过在独柱桥墩上端增设盖梁，增加横桥向支撑点的数量，以达到提高独柱墩桥梁整体抗倾覆稳定性的目的。在强烈地震的激励作用下，横桥与独柱桥墩和钢箱之间产生相对位移；当位移较小时，阻尼限位器模块提供相对较低的刚度和强度。在强烈的地震激励下，位移响应增加，阻尼限位器模块提供更高的强度，同时提供更高的刚度。阻尼限位器模块提供的刚度，可以限制横桥和独柱桥墩之间的相对位移。
