摘要:结合某三跨连续梁桥的施工过程，利用Midas软件建立了有限元计算分析模型，按照该桥的悬臂法浇筑施工过程，对桥梁进行仿真分析。根据实际监测数据，对施工过程进行控制。计算和现场实测数据结果表明：梁体各监控截面的应力实测值与计算值较为接近，在安全范围以内；主梁线形控制较为得当，合拢后整体线形比较平顺，达到预期目标，满足设计要求，达到了桥梁施工监控的目的。本桥的施工控制过程研究可以作为同类桥梁的参考借鉴。

Abstract: Combined with the construction process of three span continuous beam bridge, a finite element analysis model was built by using Midas software. According to the process of cantilever construction of the bridge, the simulation analysis of bridge was completed. According to the actual monitoring data, construction process could be controled. Calculation and field test data shows that: each monitoring section beam should be calculated value and themeasured value is in the safe range; beam shape control is more appropriate, after the closure of the overall alignment more smoothly, to achieve the desired objectives, meet the design requirements, achieve the purpose of bridge construction monitoring. The bridge construction controlprocess can be used as a reference of similar bridge.
