An improved anchor wall includes a series of vertical caissons cast in place along a line defining the boundary of the wall. Soil is executed from one side of the line and anchor rods are used to attach the caissons to the remaining soil. Discrete panels are then stacked one upon the other and attached by a reinforced concrete rib to the vertical caissons.
