Description

Anti-seismic device for highway bridge

Technical Field

The utility model relates to the technical field of bridge earthquake resistance, in particular to an earthquake-resistant device for a highway bridge.

Background

Ground cracks can cause shortening, lengthening or sinking of the bridge span. When an earthquake occurs, the earthquake waves not only generate vertical vibration force, but also generate larger horizontal force, so that the bridge is finally damaged due to different stress of the bridge piers. As most bridges in China are selected according to the industrial standard when the bridge supports are adopted, the influence of the horizontal rigidity of the piers on the service life of the bridge structure is not considered, or the rigidity of the piers is changed to adapt to the requirements of the bridge structure. Therefore, when the heights of the bridge piers of the bridge are different, the rigidity of each bridge pier is different, and the higher the height of the bridge pier is, the smaller the rigidity of the bridge pier is. If a common bridge support is adopted, the horizontal rigidity of each stress point in the whole bridge system is inconsistent. In the operation of the bridge, a situation that a part of the bridge piers participate in the operation and another part of the bridge piers do not participate in the operation is generated, which is very disadvantageous to the service life and the service life of the bridge structure, so that improvement is needed.
