Construction Control Of Moveable Steel-box Bridge

Construction of the bridge span to go through a complex process, in the process will be determined by many factors and uncertainties, leading to the actual state of the bridge structure and deviation from theoretical analysis of the state. Therefore, control of key bridge construction is through the right course of construction of the deviation of identification, identify problems and timely corrective, while the structure of the follow-up phase to predict the final Shi completion state to meet the design requirements.First of place,The bridge construction theory was expounded in this article, briefly introduced the status of bridge construction, control the content and methods of influencing factors. Meanwhile at home and abroad have been on the Moveable Steel-Box Bridge, based on Moveable Steel-Box Bridge on the Haihe River construction monitoring for the background, Moveable Steel-Box Bridge construction monitoring methods, control of focus, the establishment of Moveable Steel-Box Bridge finite element model calculations, on the completion state was simulated, and the construction process are key conditions of displacement and stress analysis of a detailed calculation, the system summarizes the Moveable Steel-Box Bridge. Alignment control and stress control methods, focusing on the construction of linear control of a detailed description of the process, and construction monitoring detailed testing data analysis, and conclusions drawn certain law, for the construction of similar bridges provide reference control.
