Abstract:

In June and July 1983, the Oregon State Highway Division constructed a geogrid-retained soil wall to stabilize a landslide on the Oregon coast. The project was an FHWA Experimental Features Project. The experimental aspects of the project were to assess construction problems of near-vertical walls with high-density polyethylene geogrids and to investigate the feasibility of establishing vegetation on the wall face to provide a natural appearance at an esthetically sensitive site. The experience gained in the design and construction of the geogrid wall is presented. Problems encountered during construction are discussed and recommendations are made for improved methods for future application. It is concluded that geogrid wall construction is practical. Geogrids are more labor intensive than conventional geotextiles, but their greater strength and ultraviolet light resistance are compensating advantages. Establishment of vegetation on the face of a geogrid wall is possible by placing sod strips between the backfill and the geogrid. A coarse backfill or a filter fabric should be used if sod is not placed against the face to limit the loss of fines.
