Abstract
Precast modular concrete wall blocks are assembled to form a retaining wall in front of a limited depth cut wall face. Arched confinement cells are formed behind the courses of blocks by sections of vertically oriented sheet material for reception and retention of a particulate fill material. Each wall block is provided with a channel or slot for attaching opposed edge portions of the cell-forming sheets of material to the rear surfaces by an interference fit or by comb-like grid connecting devices to define generally semi-circular confinement cells to reinforce the retaining wall. The fill material uniformly flexes the cell-forming sheet material and also surrounds the space between the confinement cells and cut wall face.
