谈顶推连续箱梁施工监控技术

Discussion on the construction monitoring technology of pushing continuous box girder

依托广梅汕连续箱梁顶推施工实例,从连续梁顶推施工结构受力、几何形态、墩身受力、墩间空间、线形等方面对连续梁、墩身、导梁进行了各种工况施工监控,获得了基础数据,为安全顺利施工提供了依据。

Based on Guangmeishan railway continuous box girder pushing construction example,starting from aspects of continuous box girder pushing construction structure stress,geometrical morphology,pier stress,pier space and linear control,the paper carries out construction monitoring under the construction conditions of continuous beam,pier and guiding beam,and obtains basic data,which has provided some guidance for smooth construction.
