Abstract
The Bell System emphasis on burying the transmission media plant directly in the soil resulted in the initiation of a study in 1956 designed to determine the behavior of commercial and experimental materials in the soil. For this study, two test sites representative of soils of large sections of the country were employed: one in Bainbridge, Georgia, and the other in Roswell, New Mexico, typical acid and alkaline soils, respectively. The soil characteristics, test plot design, sample preparation, installation and removal schedules, and overall areas of responsibilities are discussed in this paper. A detailed discussion of the effect of up to eight years of soil burial exposure on molded plastics, casting resins, rubbers and metal-to-rubber bonds, electrical and structural laminates, adhesives, tapes, and coated conductors are covered in companion papers. The history of the problems with buried structures and the engineering implications are stressed.
