(安徽大学交通分校合肥 230051)

提要介绍了采用橡胶支座的简支梁桥抗震计算的理论、方法及抗震措施,并以江苏宿迁桥抗震设计为例,分析
纵桥向、横桥向地震作用力计算过程。计算结果显示,江苏宿迁桥在地震时下部由地震作用力控制,纵桥向、横
桥向水平力均较大。研究结果显示, 桥梁设计应在详细的调查基础上,只有把合理的抗震设计和有效的抗震措施
结合起来,才能收到好的效果。

Abstract A calculation method of earthquake-resistance design of simply-supported girder bridge using rubber
branch seats is proposed. With the example of the Suqian Bridge, the earthquake induced stresses in both vertical
and horizontal directions are analyzed. The results show that the lower part of the bridge is controlled by
earthquake induced stresses,with large vertical and horizontal stresses. It can be concluded that good bridge design
can only be achieved through bination of scientific design methods and effective earthquake-resistance
measures.
Key words simply-supported girder bridge,earthquake resistance,vertical and horizontal stresses
