The invention discloses a retaining wall structure, particularly discloses a retaining wall structure for sponge city construction, and belongs to the technical field of city landscape and river regulation structures. By means of the retaining wall structure for sponge city construction, water can be delivered to dams on the both sides of a river channel on rainy days, and water stored in the dams on the both sides of the river channel can be delivered to the river channel in case of water shortage in the drought period. The retaining wall structure comprises a concrete or slurry stone-laying retaining wall structure body, and further comprises a drainage system and a reverse water permeation system. The drainage system is arranged on the middle lower portion of the concrete or slurry stone-laying retaining wall structure body in the vertical direction. The reverse water permeation system is arranged on the middle upper portion of the concrete or slurry stone-laying retaining wall structure body in the vertical direction.
