| 摘 要： | 以四跨连续梁桥减震桥为例,采用动态时程分析方法对该桥梁的常规抗震方案及采用铅芯橡胶支座减震方案进行了对比计算,对桥梁的水平向和竖向地震反应进行了分析,计算结果表明,当遭受强地震作用时,减震桥梁相对于抗震方案桥墩水平位移可以得到显著地降低,桥梁的竖向地震反应是不容忽视的。

| Abstract: | A continuous girder bridge adopting lead rubber bearing as seismic reduction device was analyzed with time history method, the results were compared with the traditional design method.The vertical and horizontal seismic response of the bridge was analyzed.The results show that when the seismic bridge meet great shock, the piers'horizontal displacement is reduced greatly, when the bridge is being designed,the vertical seismic response must be considered. |
