摘要
为保证长沙市机场大道工程跨磁悬浮钢箱梁顶推施工的安全性,利用有限元软件Midas对主梁和导梁进行了数值计算分析,提出了设计优化方案。通过对施工过程现场监测,并对结果进行分析,验证了设计优化方案的可行性,并为类似工程提供了参考意义。
In order to ensure the safety of Incremental launching method of steel box girder crossing magnetic suspension in Changsha airport road project.The finite element software Midas is used to analyze the main beam and guide beam,and the design optimization scheme is put forward.Through the analysis of the site monitoring results of the main beam and guide beam during the construction process.The feasibility of the design optimization scheme is verified,and the reference significance for similar projects is provided.
