Abstract :
In order to forecast structure state of bridge, Grey System Theory and recursive least squares method are applied on construction control. Composite forecasting method consisting of grey model GM(1,1) and recursive least squares method is put forward. In this method, grey model GM(1,1) is used to forecast the future state of bridge and recursive least squares method is used to amend parameters of GM(1,1) based on new data, so grey model GM(1,1) is not established repeatedly in the course of construction control. The accuracy of composite forecasting method is satisfied with the requirement of engineering and the calculation process is convenient.
