Stabilizer suitable for underground strong-motion seismograph

The utility model provides a stabilizer suitable for an underground strong-motion seismograph. The stabilizer comprises a top plate, a plurality of driving parts, a plurality of movable supporting pieces, an inclinometer and a controller. The plurality of driving parts are uniformly distributed and fixed on the top plate along the circumferential direction of the top plate, the top end of each movable supporting piece is connected with the corresponding driving part, the angles of the movable supporting pieces are adjusted by the driving parts, and the top plate is rigidly connected with an underground strong motion seismograph through a connecting piece; the inclinometer is rigidly connected with the underground strong-motion seismograph and is used for measuring an inclination angle signal of the underground strong-motion seismograph; and the controller is used for receiving the inclination angle signal and controlling the driving part to adjust the angle of the movable supporting piece through the inclinat
