Abstract:In order to minimize the cost of earth retaining structures, particularly for the low to medium height retaining walls required by highway departments, a new design of retaining wall was investigated. This utilized facing panel units anchored into a cement stabilized compacted fill. Only short anchors are required to retain the facing panels, as mechanical stabilization of the cross-section is achieved by the addition of about 7% cement, rather than by reinforcing strips. The feasibility and applicability of this design has now been demonstrated, on the basis of this study which included laboratory testing, numerical and physical modeling, and full scale construction and instrumentation of two experimental retaining walls. Specifications have been prepared and these have been refined on the basis of full-scale experience.
