A Study On Linear Construction Control System Of A Cable-Stayed Bridge

With the employment of high-strength structural materials and the development ofconstruction technique method, the Cable-Stayed Bridge will be more light and flexible.And its span is larger. The Cable-Stayed Bridge is high-Statically Indeterminate Structure.During its construction, the variation of structural internal force and main beam linear isvery complicated. Meanwhile, there is much uncertain factor. Therefore, the constructioncontrol is very important to the Cable-Stayed Bridge. In particular, its successful linearcontrol is related to the Structural safety of the state of the whole bridge.First, the thesis introduced the present situation of the Cable-Stayed Bridge’sconstruction and construction control. Second, it summarized the linear constructioncontrol of the Cable-Stayed Bridge, including importance, main contents, supervisingmethod, factor, pre-control theory and construction control system, and Artificial Neuralnetwork is help for the linear construction control of the Cable-Stayed Bridge. Third,Taking the adaptive control method for the supervising method, based on the plan of theconstruction control of a Cable-Stayed Bridge, the thesis established a BP neural networkprediction model for axis deviation of main girder, and put forward a construct controlsystem which included construction control organization management, data management,structural states monitoring, structural simulation analysis, and safety early warningmanagement. Finally, the thesis designed a software for the bridge’s linear constructioncontrol system, and introduced the function of its main modules. After that, the thesis usedthe prediction model of axis deviation for a Cable-Stayed Bridge, the application value ofBP neural network and the linear construction conctrol system for the Cable-StayedBridge’s pre-control is verificated.
