为实现桥梁施工精细化控制的要求,文章以湖北某连续梁桥为工程实例,研究了如何在合理分析结构敏感参数的基础上,有效的应用有限元修正技术,对结构仿真计算模型进行修正,将修正过后的计算模型用来指导施工实践。结果表明,将敏感参数分析与有限元模型修正技术有机结合,不但能保证监控过程中结构线形合理及受力安全,而且能更好的提高施工控制的精度,该方法具有较强的工程应用价值。
In order to meet the requirements of fine control of bridge construction, the paper takes a continuous girder bridge in Hubei Province as an example to study how to apply the finite element correction technology effectively and correct the structural simulation calculation model based on the reasonable analysis of structural sensitive parameters. The revised calculation model will be used to guide the construction practice. The results show that the combination of the sensitive parameter analysis and the finite element model correction technology can not only ensure the linear and reasonable structural safety during the monitoring process, but also improve the accuracy of construction control. This method has strong engineering application value .
