摘 要: 文章基于佛山市桂澜大桥连续箱梁悬臂施工实例,阐述了大桥施工线形监控的内容及方法,并利用有限元模型对该桥各施工阶段的累计挠度和预拱度值等线形指标进行了计算分析。 Based on the case of continuous box girder cantilever construction of Foshan Guilan Bridge,the article described the content and methods of bridge construction linear monitoring,and made the calculation and analysis on the lin-ear index of accumulative deflection and pre-camber value at each construction phase through the finite element model.
