The invention discloses a test device for servo control of deep rock mass deformation by using a rigid bearing plate center hole method, and a method for the device. The test device comprises a load control device, a force transmission device and a surface and deep part deformation measurer. The device is characterized in that the force transmission device is a jack, of which the upper end contacts a force transmission column; a top plate is arrange above the jack and contacts the top of a hole; the lower end of the jack contacts a force transmission laminating plate; a bearing plate is arranged below the jack and contacts a rock mass surface; communicated holes are formed at the centers of the force transmission laminating plate and the bearing plate below the jack and connected with rock mass boreholes, namely displacement of different depth points in the rock mass boreholes is subjected to deep displacement deformation measurement by virtue of connection of a measuring bar and a displacement sensor by usin
