The invention provides an underflow energy dissipation structure for allowing flaring piers to extend to a stilling basin. The underflow energy dissipation structure comprises the stilling basin, themultiple flaring piers, multiple gate holes and flow diverting piers; the stilling basin is arranged on the downstream side of a gate pier; the multiple flaring piers and the multiple gate holes are arranged at the outlet end of the gate pier at intervals; the flow diverting piers are located in the stilling basin and directly face outlets of the gate holes, and the quantity of the flow divertingpiers is consistent with that of the gate holes; the upstream edges of the flow diverting piers and the tail ends of the flaring piers are located on the same horizontal line; the upstream starting width of the flow diverting piers is equal to the width of the outlets of the gate holes directly facing the flow diverting piersl; and the height of the flow diverting piers is 1/5-1/3 of the water depth of the outlets of the g
