Every year thousands of miles of low standard roads are constructed in the world. Many of these, including most of those constructed for the U.S. Forest Service in the northwestern United States are located in steep and frequently unstable mountainous terrain. There is a great need for earth retaining structures which are inexpensive, flexible, and convenient to build at remote sites. Development of a fabric retained earth wall concept shows promise as one solution to this problem. Fabric retained walls consist of horizontal sheets of fabric layered in a compacted backfill soil. This provides stability of the soil mass. Each sheet is folded up over the edge of the covering soil layer and over-lapped by the next higher sheet to retain the soil face. This paper reports model studies at Oregon State University sponsored by Crown Zellerbach and describes the design and the construction by the U.S. Forest Service of a full size test wall in the Siskiyou National Forest. These tests demonstrate the feasibility of the design and construction of fabric retained earth walls and justify further development of this method of construction.
