摘　　要：采用全桥组合有限元分析思想,数值模拟分析了金水河三跨预应力混凝土连续箱梁桥的施工过程,并根据施工阶段仿真分析结果,对桥梁的应力、位移和施工预拱度进行了研究,为该桥的施工控制提供了参考依据。The cantilevered construction stages of the Jinshui River Bridge were simulated by the full bridge finite element analysis method,which was composed of three-span prestressed continuous box girder beam. And depended upon the results of simulation analysis in the construction stage,the stress,displacement and construction camber of the prestressed concrete continuous beam bridge were studied,provided reference basis for the bridge construction control.
