Combined arrangement method for reservoir release structures under pumped storage power station

A combined arrangement method for reservoir release structures under a pumped storage power station comprises the steps that a diversion tunnel, a blow-off pipe and a vertical shaft spillway tunnel are arranged, the axes of the diversion tunnel, the blow-off pipe and the vertical shaft spillway tunnel are arranged in a crossed mode on the plane and do not interfere with one another, the blow-off pipe is communicated with the vertical shaft spillway tunnel, and the included angle between the axis of the blow-off pipe and the axis of the vertical shaft spillway tunnel is set according to terrain conditions; the diversion tunnel and the vertical shaft flood discharge tunnel are communicated and share a water recession tunnel section and an outlet section, the included angle between the axes of the diversion tunnel and the vertical shaft flood discharge tunnel is not larger than 60 degrees, the blow-off pipe comprises a blow-off pipe inlet section, a pipe body section and a blow-off pipe outlet section which are
