The invention provides a rock burst tunnel yielding supporting structure which comprises a bottom plate and a tunnel supporting frame, the tunnel supporting frame is vertically arranged on the bottom plate through a flexible assembly, the flexible assembly provides elastic support for the tunnel supporting frame in the vertical direction, and a rigid supporting component is further arranged between the tunnel supporting frame and the bottom plate. And the tunnel supporting frame is rigidly supported by the rigid supporting component after the flexible transition of the flexible component. The tunnel supporting frame is flexibly supported through the flexible assembly, so that the tunnel supporting frame for supporting a tunnel can release part of impact force when receiving positive pressure, the rigid supporting component limits the tunnel supporting frame to continue to move after the flexible assembly conducts buffering transition, and then rigid supporting is provided for the whole tunnel; the supporting
