Twelve large-diameter buried conduit sections of various shapes were tested at different overpressure ranges to make an empirical determination of the degree of personnel protection afforded by commercially available steel and concrete conduits at depths of burial of 5, 7.5, and 10 feet below grade. Measurements were made of free-field overpressure at the ground surface above the structure pressure inside the structures acceleration of each structure deflection of each structure dust inside each structure fragmentary missiles inside the concrete structures and gamma and neutron radiation dose inside each structure.
