A bridge rotation space trajectory monitoring system comprises a laser vertical projection and horizontal monitoring device, a rotation process monitoring device and two sets of rotation positioning devices, the laser vertical projection and horizontal monitoring device is installed at the end of a bridge, and the rotation process monitoring device and the rotation positioning devices are both installed on the ground. The swivel process monitoring device is located on a ground theoretical projection trajectory, and the two swivel positioning devices are located at the starting point position and the final point position of the ground theoretical projection trajectory respectively. The laser vertical projection and horizontal monitoring device is used for monitoring a horizontal movement track line of the bridge; the rotation process monitoring device is used for monitoring the deviation value between the bridge rotation process and the theoretical rotation; and the swivel positioning device is used for observ
