Earthquake disasters are natural disasters which greatly affect human society, have outburst performance and unpredictability, China is a country with multiple earthquakes, and all the earthquake disasters in the past show that bridge engineering is the link which is most easily damaged by earthquakes in a road traffic system, and larger secondary disasters and indirect economic losses can be caused once the bridge engineering collapses. In order to ensure the safety of people's lives and properties, the work of earthquake resistance and disaster prevention is increasingly being paid attention.
Earthquake damage investigation shows that bridge support damage and beam falling are quite common earthquake damage, and in order to prevent the earthquake damage, an earthquake-proof stop block is an important earthquake-proof construction measure. Rigid collision between such an anti-seismic stop block and a beam often causes excessive collision force, and if the strength of the stop block is low, the stop block is likely to be damaged too early, and the beam falling prevention function cannot be sufficiently exerted, and if the strength of the stop block is high, the destruction of a substructure is likely to occur.
The seismic isolation and reduction design of a bridge structure is a main means of seismic isolation and reduction design of the bridge, and the main seismic isolation and reduction design means at home and abroad at present is that a seismic isolation and reduction support is arranged between pier beams, a seismic fortification system of the seismic isolation and reduction support is arranged, and large relative displacement is generally required to be generated between the pier beams so as to prolong the structural period and reduce the seismic action of the structure. In order to ensure the normal function of the bridge seismic isolation and reduction system, for the traditional seismic stop, the clearance between the stop and the beam body is larger than the allowable displacement of the seismic isolation and reduction support, and the clearance of the stop in a general high-intensity area is larger, so that the stop cannot play a limiting role under the action of medium and small earthquakes.
