Intelligent Active Correction Technology and Application of Tower Displacement in Arch Bridge Cable Lifting Construction

In order to control the tower deviation in the cable hoisting process of long-span concrete-filled steel tubular arch bridge during construction monitoring, a practical method of tower deviation correction was studied and established. In the paper, based on the studies about the deviation error form...
