为更好地控制连续梁桥的成桥线形，采用Midas／Civil进行有限元建模，对于悬臂施工中临时固结的简化模式及桥墩刚度参数的影响进行分析，探索了三跨PC连续梁桥施工过程中临时支座拆除前后的主梁线形变化，经数值结果与实测数据对比，推荐出合理的临时固结模拟方法；在此基础上探讨了桥墩刚度在体系转换环节对主梁线形的影响，进一步验证了该计算方法的合理性和科学性。得出的结论对同类型桥梁的施工监控过程分析具有一定的指导意义。

In order to get a better construction and supervisory control of the continuous beam bridge , by using the method of the finite element program of midas /civil , a temporary simplified consolidation model for the can-tilever construction and the pier ’ s stiffness parameters were analyzed .The linear change of the main beam is ex-plored during the construction of the three-span PC continuous beam bridge before and after the dismantling of the temporary mount .With the comparison of the experimental data analysis , a practical temporary consolidation simulation method is finally got .The impact of the linear change of the main beam by the bridge pier ’ s stiffness during the structure system conversion is studied , and the practical of this method is verified .The conclusion can give certain references to the construction of the same type bridge .
