Background

China is vast in breadth, numerous in mountains and rivers, and river-crossing bridges and road bridges are even countless. In many areas, bridges are the key of road smoothness, especially in recent years, earthquakes frequently occur, when earthquake disasters come, the damage of bridges in earthquake areas, if the most serious, such as beam falling, directly causes the interruption of life lines, hinders the progress of disaster relief actions, increases lives and properties and indirect economic losses, and brings difficulty to recovery and reconstruction after disasters. Therefore, the improvement of the seismic performance of the bridge is not easy.

The existing method for improving the seismic performance of the bridge is to adopt a support with the seismic performance, and specifically comprises a friction pendulum seismic isolation support, a stay cable seismic isolation support, a lead core seismic isolation rubber support and a high-damping seismic isolation rubber support. The friction pendulum seismic mitigation and isolation support adopts a simple pendulum principle to absorb shock, the shock absorption effect is obvious, but vertical displacement can be generated in the swing process, the side internal force influence is added to the structure, and the service life of the support is short; the lead core vibration isolation rubber support and the high-damping vibration isolation rubber support have good energy consumption capability and self-resetting capability, but are low in bearing capacity and poor in rubber aging resistance. The inhaul cable shock absorption support can solve the problems, displacement between the upper support plate and the lower support plate when the inhaul cable is additionally arranged on the side face of the support to reduce earthquake can be effectively prevented from falling, and the anti-seismic performance is improved.
