The utility model discloses a system utilizing tunnel drainage to generate electricity, which comprises a tunnel, a central drainage pipe is assembled in the middle of the tunnel, a right ditch and a left ditch are assembled on two sides of the tunnel, and the central drainage pipe is connected to a sedimentation tank through a diversion ditch. And the pressure forebay connected with the sedimentation tank in parallel is connected to a power plant through a water conduit. According to the utility model, after the underground water discharged from the central drainage ditch and the two side drainage ditches of the tunnel is gathered, the discharged underground water is filtered through the diversion ditch and then introduced into the sedimentation tank, silt in the underground water can be settled in the sedimentation tank, and then the underground water can enter the pressure forebay. The huge elevation difference between the pressure forebay and the power plant is used for generating electricity, and the gen
