Abstract: Soil nailing is the reinforced-earth idea (in which the earth must be backfilled behind the wall) applied to cut situations. Soil nails are an inexpensive post-tensioned tieback, consisting essentially of a reinforcing bar which is grouted in a hole in the ground. Also in the name of low cost, the wall is made of steel reinforced shotcrete. One of the first U.S. applications is in stabilizing a slope beside the Cumberland Gap highway in Kentucky. The article gives highlights of that project, and describes the design technique.
