摘要

When a design was needed for a 50-foot tall retaining wall, the solution was achieved using the Retension~(TM) system, a precast concrete fascia with an attached precast concrete box. The box serves as a form for a cast-in-place concrete column. The wall was founded on a cast-in-place footing bearing on competent rock. Reinforced concrete was placed into the "form" made by the precast box. Two-rock anchors cast into the column stabilized the resulting pillar. Above the rock line, galvanized tie strips were added to the back of the fascia and connected to discrete metal reinforcing strips in a granular backfill matrix similar to a Reinforced Earth wall. Advantages of the system to the contractor were cost savings due to the precast fascia units with precast "forms" attached, small footings and little backfill. This system is ideally suited for retaining walls in a rock-cut where only tied-back columns are needed, or partial rock-cut where tied-back columns are used in the lower strata and reinforcing strips in a granular backfill are added in the upper layer with no change in appearance to the fascia.
