Abstract
Precast concrete wall panels are assembled to form a retaining wall in front of a cut wall face. Arched confinement cells are formed behind the wall panels by sections of vertically oriented sheet material for reception and retention of a particulate fill material. Preferably, flat, precast concrete wall panels provided with vertically oriented tabs of integral geogrid projecting rearwardly from opposite sides of a rear face thereof which are connected to opposite end portions of a length of vertically oriented geogrid by a Bodkin joint. The thus formed confinement cells are generally semi-circular. The fill material initially used fills the confinement cells and then the space around the confinement cells and in front of the cut wall face. The wall panels are vertically staggered and successive courses of confinement cells are filled until reaching a desired height for the retaining wall.
