Abstract:

The objective of this study was to review the existing theory and concepts pertaining to the use of backpacking materials around deeply buried protective structures and to provide a unlimited evaluation of a number of commercially available products in order to determine their suitability for use as backpacking. The basic theory, concepts, and applications pertaining to the use of backpacking around buried structures were compiled and are reviewed. Based on the premise that a one-shot, one-material backpacking system will be adequate for the requirements of a deeply buried structure, a number of backpacking design considerations were established. A cursory examination and review were given to 42 materials from 9 groups of materials to determine their practicality for use as backpacking. The groupings of materials by types include granular materials, honeycombs, low-density concretes, flexible and rigid foamed plastics, and foamed rubber, glass, metal, and sulfur. None of the materials investigated and reviewed appear to satisfy all of the design considerations established for a backpacking material however, this does not discount their being used as backpacking. The ultimate selection of a backpacking material should depend on the actual service conditions the material will be subjected to and these conditions may include some of the design considerations that the material in question cannot satisfy.
