摘　　要：文中以泉州市金屿大桥工程为背景,基于MIDAS/CIVIL对主跨连续梁桥和连续刚构桥两种设计方案进行主桥地震响应分析与抗震性能验算。结果表明,在E1、E2地震作用下,两种设计方案最大弯矩均出现在中墩的墩底截面,采用减隔震支座后空心板式墩连续梁桥在地震作用下的抗震性能更佳。地震响应成为连续刚构桥设计主要控制因素之一,可通过空心板式墩桥梁地震响应分析与抗震性能研究,为类似桥梁设计方案比选提供参考。Relying on the engineering background of Jinyu Bridge in Quanzhou City,this paper analyzes the seismic response of the main bridge and calculates the seismic performance of the main bridge based on the two design schemes of continuous girder bridge and continuous rigid frame bridge by MIDAS/CIVIL.The results show that the maximum bending moment of both design schemes under El and E2 seismic effects occurs in the pier bottom section of the center pier,and the seismic performance of the hollow slab pier continuous girder bridge under seismic effects is better after adopting the damping bearings.Seismic response becomes one of the main control factors for the design of continuous rigid bridge.Through the hollow slab pier bridge seismic response analysis and seismic performance research,for similar bridge design program se-lection to provide reference.
