The utility model discloses a circle center measuring prism device which comprises a main shaft rod, a dynamic balancing device used for maintaining a prism to be in a horizontal state is connected to the end portion of the main shaft rod, and the prism connected to the dynamic balancing device is always kept horizontal by means of liquid liquidity and stable liquid with certain viscosity packaged in the dynamic balancing device. The included angle between the movable supporting leg and the main shaft rod is controlled to be equal, the prism device is erected on a chord of a stroke arc on a known arc, the sighting sight line of the dynamic balancing device is perpendicular to the chord, and the prism device is arranged on the main shaft rod and is used for supporting and fixing the main shaft rod and the prism on the main shaft rod. Therefore, the circle center position of the known arc is measured according to the principle that the vertical bisectors of the two chords on the same arc or the concentric arc i
