ABSTRACT:
A retaining wall anchoring system for a segmental retaining wall comprising a plurality of tieback rods adapted to be embedded into soil or rock with a proximal portion extending therefrom, at least one elongated force distribution member positionable directly adjacent the proximal portion of at least one of the tieback rods, a washer positionable about the proximal portions of the tieback rod in abutment with the force distribution member, and a fastener fixedly securable to the proximal portion of the tieback rod to securely clamp the washer against the force distribution member such that tensile forces imposed on the tieback rod are transmitted to the force distribution member so as to distribute these forces throughout a portion of the retaining wall.
