| 摘 要： | 减隔震设计逐渐成为结构抗震设计的重要方法,本文以云南省龙江大桥保山岸引桥为例,对使用了铅芯隔震橡胶支座的减震方案与传统的抗震方案进行了分析比较。验证了在高震区使用铅芯橡胶支座对桥梁进行减隔震设计,与传统的硬性抵抗方式相比,在经受大震时,墩柱所受到的剪力和弯矩值可以大幅降低。

| Abstract: | Taking Baoshan Bridge approach bridge of Longjiang Bridge in Yunnan Province as an example, this paper analyzes and compares the scheme using lead core isolated rubber bearing with the traditional one. Compared with the traditional rigid resistance method, it is proved that the shear force and bending moment of the pier column can be greatly reduced when the bridge is designed with lead core rubber bearing in high seismic area. |
