Research On Swivel Construction Monitoring And Control Technology For Railway T-shape Rigid Frame Bridge Of(48+48)m

In New Railway Engineering of Jinchi line across the shenshan railway T-shape rigid frame as the research background, describes the composition and construction control points swivel system, summed up the matter before the swivel various needs attention. For structural features of this bridge, the development of construction with suitable monitoring program.The paper uses Midas civil 2010 to establish the simulation model for simulation analysis.T-shape rigid frame system power draw state and main beam linear variation and variation throughout the construction process at a critical cross-section by each construction phase.In jinchi T-shape rigid frame of railway engineering construction monitoring the implementation process, by collecting and analyzing data on the strain and look for reasons for the deviation of the actual value and the theoretical value, so that the model is closer to the actual structure of the situation, thereby guiding full-bridge various stages of construction. Twist on T configuration before weighing experiments, T-shape rigid frame reasonable counterweight to ensure the safety swivel T-shape rigid frame.
