The invention discloses a full-automatic control method of bridge rotation construction, comprising the steps of (1) acquiring a rotation real-time data signal of a swivel bridge, wherein the rotation real-time data includes real-time distance data, final distance data, real-time angle data Beta, final angle data o, original angle data Alpha, with Beta=Alpha-o; (2) subjecting the rotation data real-time signal of step (1) to real-time comparison processing; (3) issuing a command to a jack according to the real-time comparison results so that the jack drives a bridge to rotate, finishing full-automatic control of bridge rotation construction. Dynamic data can be collected in time so that data acquisition and processing match with adjustment speed during rotation of the bridge, and emergent problems occurring in the rotation of the bridge can be found and handled in time.
