Abstract
A concrete revetment is provided which is arcuate in horizontal cross section, and has end portions which are interconnected by a cordal member. The cordal member is adapted to be prestressed by a tension rod to place the cordal member in compressive stress and the arcuate portion of the revetment in tensile stress. The revetment is held in place by anchor means embedded in back-fill on the convex side of the arcuate revetment. A plurality of revetments may be arranged and interlocked horizontally and vertically to form a revetment wall.
