摘　　要：桥梁施工的控制是桥梁施工技术中重要的环节之一。本文以某钢箱系杆拱桥工程项目为例,利用Midas/Civil有限元分析软件,对下承式钢箱系杆拱桥进行建模分析。对施工过程中的结构内力和位移等进行监控,对比理论数据与实际监控数据,控制拱桥的施工过程在允许的误差范围内。研究表明,模拟计算数据与实际监控数据在允许的误差范围内,为现场的施工提供了一定的理论依据。The control of bridge construction is one of the important links in bridge construction technology.Takeing a steel box tie arch bridge project as an example,this paper uses the Midas/Civil finite element analysis software to model and analyze the underbearing steel box tie arch bridge,monitors the internal forces and displacements of the structure during the construction process,and compares the theoretical data with the actual monitoring data,so as to control the construction process of the arch bridge within the allowable error range.The results show that the simulation calculation data and the actual monitoring data are within the allowable error range,which provides a certain theoretical basis for the site construction.
