| Abstract: | The GM(1,1) model for predicting the bracing form height of the beam of large scale prestressed concrete PC continuous rigid frame bridge cantilevered casting construction was established based on the gray system theory.Then the model was corrected by the residual GM(1,1) model.The application in engineering showed that the predicting precision of the bracing form height of the beam was good enough to meet the demand in engineering. |
