DESIGN PROCEDURES FOR SLIDE SUPPRESSOR WALLS

A slide suppressor wall is a retaining wall that is embedded in a slope that has failed. Slide suppressor walls are used to repair shallow slope failures in areas where right-of-way is restricted and the slope cannot be flattened. The design procedure for slide suppressor walls assumes that earth pressure acting on the wall is equal to a hydrostatic pressure of a fluid with a density equal to the total unit weight of soil. The performance of the supporting drilled shafts and load-carrying capacity of the wall panels were evaluated for a range of wall geometries. Design charts for walls supported by 18-in. and 24-in. shafts are presented. A cost study found that slide suppressor walls cost about $10 to $18/sq ft and are more economical than conventional earth-retaining structures.
