Stability Impact Analysis of Random Dead Load Distribution to T-Rigid Frame Bridge Swivel Construction

Abstract

Due to limitations of construction conditions, the swivel construction method is the preferred even required program across the highway and railway bridges. The constant contained eccentricity of swivel bridge cantilever state has a great impact on the overturning stability of swivel process. Combined with the T configuration swivel bridge engineering instance, based on the basis of data collected loads, loads theoretical model, in line with the objective variation and the scientific process and selecting the representative value of the load was explored, the cantilever pouring weight corresponding probability distribution model was analyzed, and the impact to the stability of the bridge swivel construction process was studied. The analysis of data can ensure the bridge maximum cantilever state security, as well as to provide the basis for command and decision-making of the swivel stage.
