中文摘要：

厦漳大桥地处地震高烈度区。为了解决其抗震问题,厦漳大桥北汊南引桥采用普通铅芯隔震橡胶支座和滑动限位式铅芯隔震橡胶支座混合隔震,本文通过有限元软件Ansys对其进行有限元动力分析,并与全部采用普通铅芯隔震橡胶支座对比,从理论上验证隔震支座的减震效果。

英文摘要：

Xiazhang bridge is in the high-intensity earthquake r egion.In order to address the seismic issues,Lead rubber bearing with GAP and L ead-rubber bearing（LRB） isolations are mixed-used on the north branch-south approach bridge of Xiazhang bridge.In the paper,the isolation effect of using mixed isolations on the bridge is compared with all LRB isolations,the former wa s confirmed to be significant.
