Background technique
China is located in earthquake and takes place frequently band, and earthquake of different sizes for several times occurred in history, especially in recent decades, experience
The big shake such as Wenchuan, Yaan, it is found that bridge structure destroys most serious, failure mode is mostly that fall beam broken for disaster statistics after shake
Bad and impact wreckage, brings about great losses, therefore the design of beam falling prevention stopping block is to worker to traffic operation and personal safety
For will be particularly important.Although engineer and scientific research personnel take many measures and solve earthquake bridge collision problem and fall
Beam phenomenon also constantly improve earthquake-resistant structure system, but the research of current Antivibration block still remains very big defect.
Currently, Bridges in Our Country medium and small bridges are mostly simply supported beam or continuous beam, usually in the bent cap position of bridge pier or Abutment
Concrete block is installed, when earthquake occurs, biggish lateral displacement occurs for bridge structure, and concrete block will stop girder
Movement, avoid the displacement that beam body is excessive, still, the construction measure of conventional method has ignored between bridge, bent cap and bridge pier
Connection, bridge is collided after moving with concrete block, by fierce impact due to concrete under geological process
The shear ability of block is very weak, therefore the energy of earthquake could not weaken or dissipate after occurring to hit strongly with girder, thus very
Easy failure causes to fall beam accident, causes serious casualties and economic loss.
