A B S T R A C T A retaining wall is constructed from concrete slabs laid in horizontal courses, in half-lapped relationship. The slabs are of uniform length and thickness, but of differing widths. The bottom, middle, and top thirds (approximately) of the wall are constructed respectively of relatively wide slabs, of slabs of intermediate width, and of relatively narrow slabs. A course of extra-wide anchoring slabs is provided about half-way up the wall. The front face of the wall defines a substantially planar surface, while the rear face of the wall is stepped, and the extra width of the anchoring slabs projects from the rear face of the wall. The slabs are provided with apertures, so arranged as to be in alignment when the slabs are assembled into a wall structure, forming continuous apertures extending from top to bottom of the wall. Dowell rods of metal or other suitable material, are disposed in these continuous apertures; the rods are of such dimensions as to fit inside the apertures with appreciable clearance. The completed structure is fully interlocked, since all structural slabs are locked into this structure by the dowell rods, and the structure is sufficiently flexible to be capable of substantial deformation, in response to land subsidence, frost heaving, thermal expansion and contraction, and the like, without breakage of structural elements, or loss of structural integrity.
