Abstract: A retaining wall system which uses rigid tieback elements having portions, column portions and web portions and wall panels disposed between the tieback elements. The tieback elements are designed to produce arching in the soil to reduce bearing stresses on the soil below base portions of the tieback elements by providing web portions sufficiently large to produce a complete ditch condition in the soil upon movement of the rigid tieback elements. This provides an economical retaining wall system in which multiple tiered walls can be spaced by an amount sufficient to produce a complete ditch condition. The wall can be implemented as a vertical wall or as a battered wall.

Abstract: A retaining wall system which provides an essentially a vertical wall without vertically aligned protrusions. The multitiered retaining wall system uses a plurality of tieback elements which act independently of each other to prevent the transference of forces and moments to lower tiers. The design provides a high degree of flexibility in the horizontal spacing of the tieback elements, which is independent of the width of the retaining wall panel, so as to meet specified technical conditions and allow the use of standard size prefabricated concrete components.
