Tunnel rockburst prevention and control method and system

The invention provides a tunnel rockburst prevention and control method and system, and relates to the technical field of geotechnical engineering.The method comprises the steps that the positions and the number of kerfs formed in the inner wall of a tunnel are determined according to the arc length of a tunnel haunch; the sizes of the kerfs are determined according to the number of the kerfs and the ground stress of the tunnel; and according to the size, the position and the number of the kerfs, cutting equipment is controlled to cut the inner wall of the tunnel in the axial direction of the tunnel to form the kerfs. The surrounding rock around the tunnel is rapidly and timely cut by using mechanical cutting equipment, the generated vibration is small, and the interior of the surrounding rock cannot be damaged; the kerf enables rocks which should be extruded mutually to generate rockburst after original deformation to obtain a displacement space, the surrounding rocks can close the kerf after the surrounding
