桥梁隔震装置布置方式研究

桥梁隔震装置是经济实用的抗震设备。本文分析了桥墩受地震作用破坏机理和桥梁隔震装置隔震原理。从桥墩破坏实际形式中,总结出顶底端受地震响应相对位移过大是桥墩受破坏的主要原因。将隔震装置布置在桥墩底部能有效减少传入桥墩的地震能量,减震效果优于将其布置在顶部。

Research on Disposal Mode of Isolation Equipment in Bridge

Bridge isolation equipment is economic and applied anti-seism facility. The thesis analyses the isolation principle of the bridge isolation equipment and the mechanism of the bridge pier which is destroyed by seism. According to the form of the destroyed bridge pier, it summarizes that the primary destroyed cause is that the relative displacement of the top and the bottom bridge pier is too big. The isolation equipment disposed at the bottom of the bridge pier, which is better than the one disposed at the top of the bridge, can effectively reduce seism energy introduced to bridge pier.
