| Abstract: | To find out the law of the stress variation in the cantilever construction of continuous beam bridge and to control the future status of the bridge,a number of the gray models GM(1,1) was established in accordance with the measured stress data array of different controlled cross sections of the box beam of the Huangsha Harbor Bridge that was being constructed and the models was used to predict the stress variation of the Bridge along with the proceeding of the construction.The results of the prediction are ... |
