摘　　要： 结合虎门二桥工程项目的实际,进行西、中引桥上部结构施工方案比选。针对项目采用的62.5 m跨径预制节段拼装PC连续刚构箱梁的结构形式,采用有限元分析软件Midas civil建立全桥三维杆系模型进行计算,结果满足规范要求,可为类似桥梁的设计及计算提供参考。 Considering the actual situation of the Sencond Humen Bridge, scheme comparison has been conducted for the superstructure of West and Middle Approach Bridge. As for adopting of precast segmental assembling PC continuous rigid frame box girder with the span of 62. 5 m, the whole bridge three-dimensional truss model has been established by the finite element analysis software Midas Civil 2012, and the calculation results could meet the relevant requirements of the specifications,which could provide references for design of the similar bridge engineering.
