Application of GM(1,1) Model Established by Moving Average Method in Stress Prediction of Rigid Frame Bridge Construction

Abstract:

Stress variation is complicate during the course of rigid frame bridge construction, it is difficult to grasp the development trend of stress because of too many influencing factors. When using GM(1,1) model solely, the prediction accuracy is low and it is critical to collect much raw data of stress. Method of moving average improves GM(1,1) model by processing data before modeling. The paper takes Hu Lu-ding Bridge as an example and the results show that the GM(1,1) model established by moving-average method has higher prediction accuracy and can be efficiently used in stress prediction of rigid frame bridge.
