The continuous rigid frame bridge has been widely used in practical engineering, so it has high requirement for its linear control. The Grey System Theory method is applied to the adjustment and prediction of box girder linear control in the construction control of continuous rigid frame bridge. The method is applied in the construction process of 72 + 133 + 72 m continuous rigid frame of Manjiang Bridge. According to the monitoring data, the Grey System Theory model is used to predict, and according to the prediction results and actual construction measurement results, although the measured value is different from the theoretical value, basically, they are consistent with higher prediction accuracy, which proves the good application effect of the Grey System Theory in construction monitoring.
