The invention provides a structure for improving water flow characteristics at the intersection of underground caverns and a using method thereof.The structure comprises a vertical shaft flood discharging tunnel and a water discharging tunnel, the water discharging tunnel is used for early-stage flow guiding and later-stage emptying, and the flood discharging tunnel and the water discharging tunnel intersect to form an intersection section of the flood discharging tunnel and the water discharging tunnel; an intersection section of the spillway tunnel and the drainage tunnel is communicated with the drainage tunnel after the double-tunnel intersection, a partition wall parallel to the axis of the spillway tunnel is arranged on the intersection section of the spillway tunnel and the drainage tunnel so as to separate the spillway tunnel from the intersection section of the spillway tunnel and the drainage tunnel, a bottom orifice is formed in the bottom of the partition wall, and a partition pier used for orific
