Application of SCGM(1,1) Method in the Construction Monitoring and Control of Continuous Girder Bridges

This paper bases on building grey prediction model with the stress sequence of continuous beam bridge construction control section, discusses the application of the model in the construction control of the continuous beam bridge. SCGM (1, 1) dynamic model is based on test results of control cross-sections of Nanhe Bridge have been established for prediction, on the background of the construction of Nanhe Bridge, in Jiangsu province. The example shows that the prediction precision and adaptability of the model can achieve the requirements of the engineering construction, and the feasibility and adaptability of the construction control for bridge by using this model is validated to forecast the stress value in the practical construction control for a PC continuous bridge.
