摘　　要：采用减隔震支座对主桥进行减隔震抗震设计,并对减隔震设计方案在E2地震下的动力响应进行了分析。分析结果表明,采用减隔震方案后,主桥所有构件抗震性能均得到了不同程度的优化,拉索支座提高了全结构的抗震性能。The seismic isolation design of the main bridge was carried out by using the seismic isolation bearing,and the dynamic response of the seismic isolation design under the E2 earthquake was analyzed.The analysis results show that after the seismic isolation and isolation scheme,the seismic performance of all components of the main bridge is optimized to different extents,and the cable supports improve the seismic performance of the whole structure.
