High-speed rail bridge collaborative seismic mitigation and isolation system considering multiple performance requirements
The invention discloses a high-speed rail bridge collaborative seismic mitigation and isolation system considering multiple performance requirements, which comprises a single-pin performance controllable seismic isolation support and a multidirectional shear damper, the single-pin performance controllable seismic isolation support comprises a top plate, a slip layer, a shear pin, a middle steel plate, a rubber plate, a dust cover, a steel basin and a bottom plate; a shear pin of the single-pin performance-controllable shock insulation support is arranged in the center of the support and is made of high-strength and high-brittleness steel. A clamping groove is reserved in a top plate of the single-pin performance-controllable shock insulation support, and a reserved hole is formed in a middle steel plate; the multi-direction shearing type damper comprises a driving plate, a fixing plate, a top plate, a base, a gasket, a long bolt, a cushion block and a driving column. The fixing plate of the multidirectional shear type damper is fixed through long bolts fixedly connected with the base and the top plate. The safety of a train running at a high speed and the anti-seismic safety of a bridge structure can be effectively guaranteed when an earthquake occurs, and the requirement for large rigidity of a high-speed rail bridge during normal operation can be met.
本发明公开了一种考虑多重性能需求的高铁桥梁协同减隔震体系，包括单销性能可控型隔震支座和多向剪切型阻尼器，所述单销性能可控型隔震支座包括顶板、滑移层、剪力销、中间钢板、橡胶板、防尘罩、钢盆和底板；所述单销性能可控型隔震支座的剪力销布置在支座中心，并且采用高强度、高脆性的钢材；所述单销性能可控型隔震支座的顶板预留卡槽，中间钢板设置预留孔；所述多向剪切型阻尼器包括驱动板、固定板、顶板、底座、垫圈、长螺栓、垫块和驱动柱；所述多向剪切型阻尼器的固定板通过与底座和顶板固接的长螺栓实现固定。本发明能有效保证地震发生时高速运行的列车的安全性及桥梁结构的抗震安全性，并且能够保证高铁桥梁正常运营时的大刚度需求。
