Abstract
A retaining wall having a height of greater than ten feet which includes a lower section of inextensible reinforcements and an upper section of extensible reinforcements. By the use of inextensible reinforcements in place of extensible reinforcements in a lower portion of a wall having a height greater than ten feet, the lower portion of the wall will tend to distribute the stresses of soil compaction and require less quality control/assurance during construction. Further, by the use of extensible reinforcements in the upper section of a retaining having a height greater than ten feet, the extensible reinforcements will maintain the retaining wall in place and have significantly improved corrosion resistance over inextensible metal reinforcements.
