Based on rotating construction for curved continuous girder bridge with spans (80+128+80)m on the PanYING passenger special line across HaiGou line as engineering example, arrangement method for center of gravity for curved rotating structure is introduced. It is presented that imbalance moment of rotating structure can be quickly confirmed by using spherical hinge stress, and experiment of weighing is carried out adopting spherical hinge rotating method. Reliable parameter is made for rotating construction phase and accomplished.
