Wave dissipation structure for upstream revetment of earth and rockfill dam of reservoir

The invention discloses a wave dissipation structure for an upstream revetment of an earth and rockfill dam of a reservoir in the technical field of earth and rockfill dam slope protection. The wave dissipation structure comprises a plurality of trapezoidal wave dissipation piers, wherein the trapezoidal wave dissipation piers are evenly arranged downwards at certain intervals in the dam slope direction from a wave wall; each trapezoid wave dissipation pier is composed of a straight quadrangular prism with a right trapezoid bottom surface; the side edges of the straight quadrangular prism are parallel to the dam axis, and the length of the side edges is consistent with the dam length; the bottom face of the straight quadrangular prism is perpendicular to the dam face. the waist line of the right trapezoid is basically kept horizontal and has a gradient of about 2%; the upper bottom of the right trapezoid is parallel to the dam slope line; the lower bottom of the right trapezoid coincides with a dam slope line
