| Abstract: | The optimum weighted combined model is characteristics of the maximum use of information and the minimum sum of residual squares, which is widely used in prediction. According to the funda- mental principle of optimum weighted combined theory and taking the construction monitoring of DengKou Yellow River Super Bridge in Baotou of Inner Mongolia as background, this paper presents a combination prediction model based on difference model and metabolic GM（1,1）model of grey system theory, and applies the model to forecast the stress of the girders. By comparing to the measured val- ues, the higher precision and the better stability of the optimum weighted combined model is valida- ted. A new approach is provided for the real-time prediction in the construction control of bridges. |
