Prediction of Parameters Error in Method of Construction Control in Cable-Stayed Bridge

Abstract:

To reach the optimum mechanics state of long span cable-stayed bridge after it erected, a method is proposed to predict and adjust parameter in construct control of cable-stayed bridge, which integrates the grey prediction theory model and influence matrix adjustment method compositively. The selection of parameters of construct control, reasonable objects of adjustment and determination of state variable during prediction data process are also studied deeply, and a perfect procedure and method is established to identify, predict and optimizing adjust parameters. The method is also verified by construct control of the longest span pre-stressed concrete bridge in Asia, and the effect of construct is very successful. This work of construct control can absolutely demonstrate the validity and practicability of the method.
